What is Dynamic IP - details

Every citizen has a name, surname and patronymic. This is necessary, in particular, so that the interlocutors can address a specific person during the conversation.

A computer, being connected to the Internet, must also have its own name, otherwise there will be confusion: how to send information to this particular PC, and not to some other. Or: from which machine is the data being received at the moment?

For identification, the provider that provides access to the World Wide Web is obliged to give a name to each serviced device. This name is the IP address.

Its format is a combination of digits from 0 to 9 in the form: xxx.xxx.xxx.xxx, up to 12 digits in total. Where xxx is any number from 0 to 255. For example: 92.100.86.151. The rule for assigning an address is strictly regulated, among more than a billion computers connected to the network, named addresses cannot be repeated.

In addition to PCs, IP addresses are received by all devices using the Internet: servers, mobile devices, laptops.

What is dynamic IP?

What is dynamic IP?

How dynamic IP is provided

After concluding an agreement on the provision of Internet services, the owner of the PC connects to the network, that is, through the provider's server, it connects to the network. In this case, the host gives him a "name" - the same IP-address from the number of those available at the moment. If at each connection a new IP address is assigned, then in this case it is considered dynamic.

This is beneficial for the provider, since after the Internet session, the user "returns" his IP back and the system can issue it to the next connected one. The range of addresses is limited, therefore, the higher their circulation, the more clients the provider will be able to serve.

Static IP. Differences from dynamic

Static IP is reserved for the user after the conclusion of an agreement with the company. Even if the client's PC is offline, its IP cannot be assigned to another device.

Static IP is reserved for the user and cannot be assigned to another user

Static IP is reserved for the user and cannot be assigned to another user

Internet servers have a static address, this is necessary for them to work stably, and the sites located on them can be found by the user at any time, in the same place.

On a note! The disadvantage of a static IP for a client is the need for additional payment and the possibility of a targeted attack on a given PC.

Find out the type of our IP

There are two ways to find out if a dynamic or static IP address is assigned to a PC:

  1. Go to any site that shows the current IP, for example, 2ip.ru. On the left, the address will be indicated in large numbers. We turn off the network and turn it on again, go to the same site again. If the IP has changed, then it is dynamic. This method will work on all devices and all operating systems. In any browser, open the site 2ip.ru, in the left part of the window we find our IP address

    In any browser, open the site 2ip.ru, in the left part of the window we find our IP address

  2. Call your provider's support team or find a service agreement that has all the information you need.

Changes from static to dynamic IP

To set up a permanent IP in Windows 7 and Windows 10, you need to:

  1. From the "Control Panel" find "Network and Sharing Center", on the left - the "Changes to adapter settings" tab. Go to the "Start" menu, open the "Control Panel"

    Go to the "Start" menu, open the "Control Panel"

    In the "View" category, select "Large icons", find and open the "Network and Sharing Center" section

    In the "View" category, select "Large icons", find and open the "Network and Sharing Center" section

    Click on the link "Change adapter parameters"

    Click on the link "Change adapter parameters"

  2. In the open window "Network Connections" find your connection, select it (right-click), click "Properties". In the open window "Network Connections" we find our connection, right-click on it, click on the item "Properties"

    In the open window "Network Connections" we find our connection, right-click on it, click on the item "Properties"

  3. Another window of properties will appear, in which we double-click on the item "Internet Protocol TCP / IPv4". Double-click the left mouse button on the item "Internet Protocol TCP / IPv4"

    Double-click the left mouse button on the item "Internet Protocol TCP / IPv4"

  4. Here we select the "Use the following IP address" option, enter it in the "IP address" field and use the "TAB" key to fill in the rest of the fields automatically. Further - we confirm the changes - "OK". We select the option "Use the following IP-address"

    We select the option "Use the following IP-address"

    Enter your address in the "IP-address" field, use the "TAB" key to fill in the rest of the fields automatically, click "OK"

    Enter your address in the "IP-address" field, use the "TAB" key to fill in the rest of the fields automatically, click "OK"

Important! If you need to perform the opposite action (switching to a dynamic address), then activate the "Obtain an IP address automatically" option, and again - "OK".

To get a static IP-address, activate the "Obtain an IP-address automatically" option, click "OK"

To get a static IP-address, activate the "Obtain an IP-address automatically" option, click "OK"

Dynamic IP options. Windows setup

The upfront steps in Windows are the same as changing the type from static ip to dynamic. Through the "Network and Sharing Center". Apart from the checkbox "Obtain an IP address automatically", nothing else is needed.

For dynamic IP, it may be necessary, in some cases, to specify the MAC address: copy from the settings in Windows and transfer to the settings of the router.

  1. Go to the "Network Connections" window (see point 1 above), right-click on your connection, click on the "Status" item. Right-click on your connection, click on the "Status" item

    Right-click on your connection, click on the "Status" item

  2. Click on the "Details" button. We click on the button "Information"

    We click on the button "Information"

  3. In the "Physical Address" field, copy the MAC address. In the "Physical address" field, copy the MAC address

    In the "Physical address" field, copy the MAC address

    In the router settings, open the "Network" section, then the "MAC Clone" subsection, click on the "Clone MAC Address" button, then "Save"

    In the router settings, open the "Network" section, then the "MAC Clone" subsection, click on the "Clone MAC Address" button, then "Save"

Attention! The MAC address in the properties of the network connection and the settings of the router must match .

The rest of the settings are usually determined automatically.

Configuring the router

For this step, you need to go to the router settings. This is usually done from the browser:

  1. Instead of the site name, the device's ip is entered (see the information in the manual), often it is: 192.168.0.1. Enter the device's ip into the browser line

    Enter the device's ip into the browser line

  2. If everything is correct, you will be prompted for a username and password. The default can be: admin - admin. We enter the username and password, we can find the factory settings on the back of the router, if we changed them, we enter our own, click "Send"

    We enter the username and password, we can find the factory settings on the back of the router, if we changed them, we enter our own, click "Send"

    The data for accessing the settings of the router can be found on the back of the router.

    The data for accessing the settings of the router can be found on the back of the router.

    On a note! Often written on the nameplate of the router (on the bottom of the device).

  3. The sought option should enable or disable automatic IP retrieval. For example, - "Get IP-address automatically", - acceptance of the address in automatic mode. Or: "Get Static IP-address", for permanent ip. The menus and settings may differ for different routers. Open the "Network" section, select "Dynamic IP" in the "WAN Connection Type" field, all other settings are performed automatically

    Open the "Network" section, select "Dynamic IP" in the "WAN Connection Type" field, all other settings are performed automatically

  4. After that, you will need to reboot the device. To do this, it may be enough to click the "Save" or "Save" button. Press the button "Save" or "Save"

    Press the button "Save" or "Save"

Pros and cons of two types of IP

Permanent IP is needed:

  • to organize a home Internet server that is constantly online;
  • to create a mail server;
  • if stable remote access to the computer is required.

Constant IP provides some stability, but most of the time it is not required.

Which IP address is better to use dynamic or static (permanent)?

Which IP address is better to use dynamic or static (permanent)?

Advice! Whatever IP is used, if the owner breaks the law while on the network, the relevant authorities will easily figure it out. All history of address assignment and statistics of visits are stored on the servers of the provider.

Advantages of dynamic addresses:

  • no additional payment is needed;
  • easy to change by restarting the modem / router;
  • it is difficult to hack a PC if the address changes frequently.

How to hide your true IP

The actual question that interests Internet users is changing the real IP.

What you may need for:

  • to access sites that are blocked for any reason in the country from which the network is connected;
  • anonymity;
  • the desire to hide the fact of their presence in the log files of certain resources;
  • real ah-pi is prohibited on some server.

It's no secret that in some countries it is forbidden to go to some sites, for example, in the PRC, the authorities treat YouTube badly. To bypass the blocking, you need to "cover" the IP. It happens that the user is “banned”, say, on a game server; here, too, you cannot do without changing the address.

We use methods of anonymity for the IP address

We use methods of anonymity for the IP address

Or the internet traveler simply doesn't want anyone to identify him or her online for personal reasons.

There are four ways to implement anonymity:

  • proxy server;
  • anonymizing site;
  • Thor;
  • VPN technology.

The proxy server "replaces" the original ai-pi with its own. More precisely, the user, in essence, uses the proxy as an intermediary, a traffic pass. All entries on the servers visited will be marked with its IP. There are paid ones - more reliable and faster. Free - hard to find and mediocre speed.

Anonymizing site, the same proxy, but will only allow you to navigate the Internet pages. No one will know when and what resources were viewed. Services are paid, now they are not very popular.

The free Tor browser creates a chain of proxies from all over the world, does not require money, but it does not always work quickly. The traffic is encrypted. There are versions for all operating systems.

Using the Tor browser to change your IP address

Using the Tor browser to change your IP address

The most powerful tool is VPN, "virtual private networks". A channel is created between the user's PC and the provider, through which encrypted traffic moves in both directions. Requires software - encryption client. VPN server owners will ask for payment, although there are a number of free projects.

Thus, if you do not need to create a server at home, then a dynamic IP is suitable for daily work, its constant change will not lead to any inconvenience.

Video - How to Create a Dynamic IP

Greetings to the blog, friends. Many have heard of addressing. But, not everyone has a clear idea of ​​what is IP , what it is needed for, what opportunities its presence opens up. From today's material, you will also learn what addresses are, how they differ from each other.

Today's material will be mainly theoretical and is intended for those who began to independently study the principles of building computer networks or want to expand their horizons for general development. Which is not at all superfluous in our time.

Two computers or (any other devices) connected by a network cable (or using radio waves) are already a computer network. There has long been a technology by which these two devices are combined into a network, it is called a network environment. This is a whole complex of software that can "see"

and work with different kinds of computer hardware and supports different ways to control that hardware. One of the computers generates an electrical (optical, radio) signal. The combination of these signals is a kind of binary code, which, in a certain sequence, ends up on the network card.

Further along the cable (or in another way), this data goes to the same card of the second computer. It contains software that "understands" the received code. And then everything depends on the task. In the reverse order, the received data is converted to the data that was originally “sent”. For example, you communicate with a person through a social network through text, photos and videos. As far as video differs from Morse code, the described process of exchanging data between computers is much more complicated than what I just described.

But don't be afraid of difficulties. Your computers have everything they need to do this job. A wide variety of computers can be networked using a common language that is the same for everyone. This language is called protocols. In our case, we are talking about network protocols. As a rule, computers use not one, but several network protocols simultaneously when exchanging data. All protocols comply with the same open standards, this guarantees the general compatibility of computers and eliminates obligations to any manufacturer.

In our example, there is a network of two computers. But we know that modern networks are bigger things. Likewise, the protocols differ in the complexity of the services provided and the interaction with each other when solving a specific task. For example, a computer periodically polls a neighbor by sending a certain signal like: "I am here." And each of the protocols adds a certain unique header to this data, then transfers the data to the next protocol, it adds its own header, and so on in a certain sequence to the end.

At the end, a set of data is formed, which is then transferred through a network card to the desired computer and, in reverse order, the data is processed on the receiving computer to the desired form. The thing is that a computer is a bundle of hardware (hardware) and software. In order for the signal to reach a specific microcircuit on the motherboard of your computer, it must be converted to a form that this microcircuit "understands".

And the signal must first pass successfully through the network card. This is one of the reasons for the existence of a certain number of network protocols. This number is also called the "Protocol stack". Processing proceeds "along the stack" from complex to simple and from simple to complex, although everything is relative here. The signal goes through certain levels until the final program processes it to the final result - this will be the open page of this site, or the received email.

It matters where your signals are sent. If the computer is in the next office, the data link protocol will be enough for it (Wi-Fi is an example of such a protocol). But if your signal goes to a social network, then the matter is no longer without IP (Internet Protokol). All along the chain. Your Wi-Fi router processes signals received from your PC until a certain point. But then control is transferred to the transport protocol IP and your packed signal is already flying to the address along the most optimal route (from the point of view of this very protocol).

At the speed of light, it passes through dozens of intermediate routers, is repackaged by them again, sent to the next one, until it reaches the desired one (it has the same IP that your computer wrote down in the header). After that, the signal is sent to the required server, from which the response signals are generated at the same speed and after going back, they get to the display of your monitor in the form of the required information. All this is possible thanks to the interaction of protocols TCP и IP (Transmission Control Protokol /Internet Protokol ).

The most important functions of the protocol IP is an addressing иrouting ... It programmatically contains its own addressing system for identifying computers in networks of almost any size. Everyone has heard about the version of the IPv6 protocol - it is even more powerful than the usual IPv4, its address ranges are much wider and many providers are already using them to issue static addresses.

The IP address is not assigned to the computer, but to the computer's network card. If there are two of them installed on the computer, this system will have two addresses. If there is also a router or 3g modem in the network to access the Internet, then each of these devices will be assigned its own unique "gray" IP -the address. Your smartphone uses the same standards to access the Internet, with the only difference that the services and addresses are provided by the mobile operator.

Static IP address - what is it for?

Protocol standards TCP / IP published in the early eighties of the twentieth century and described in special documents. The technology has been tested for a long time and today, when a computer is connected to almost any network, it can be assigned static or dynamic IP the address. It consists of a sequence of numbers separated by periods (octets). For example, the first value specifies the number of subnets and computers (nodes) in each subnet:

Static (or permanent) IP - the address is issued by the system administrator. If we are talking about the Internet, then the address is provided by the Internet provider. The main advantage of such an address is its consistency. A static address is assigned to a specific subscriber for the entire period of using the services of a specific Internet provider and does not change. As discussed earlier, the most important functions of the IP protocol are addressing and routing. And having your own static "white" address will allow you to solve the following tasks:

  • organize local computer networks with internal (static or dynamic) IP addresses and provide access to the Internet for selected computers in the network;
  • configure user access to databases (SQL, 1c-accounting) from almost anywhere via the Internet;
  • interconnect various networks;
  • configure file exchange via an FTP server and organize access to them from the Internet;
  • configure access from the Internet to a mail, game, file, proxy server, and so on.

Organizations, individual entrepreneurs, whose subdivisions are scattered in different areas, work this way. However, there are many ordinary people who build their private networks with the help of a dedicated static address, and sometimes quite a large number of users are united in them - for example, an entire street or a block. Since the package of services provided by the protocol IP is wider and more complex, then the cost of the services of an Internet provider with the provision of a permanent address will be somewhat more expensive.

Dynamic IP address - what is it?

Dynamic IP works exactly the same as a static address, it is almost no different from it. Its main difference is that it automatically changes every time the device is turned on / rebooted. For example, if the protocol is enabled on the router DHCP - all devices connected to it can receive addresses automatically. You turned on your smartphone and, somewhere on the server of your operator, its network interface was automatically registered under a certain address.

Dynamic IP quite enough for home use. Data packets are also sent from your computer to the network and back. But the address changes to a new one after restarting the computer, router, network card, server. An unoccupied one is selected from a certain range of addresses and your device is attached to it. This must be taken into account if you use a dynamic IP for debugging, testing ports and so on.

What does "Gray IP Address" mean?

Also, addresses are divided into "gray" and "white". The white address is the external one issued by the ISP. Let's imagine now that you have registered it on your home router. Our two home computers are connected to the router. They are assigned dynamic addresses - these are the so-called internal addresses of your home network. They are then called "gray". Access to them from the Internet is usually closed. Therefore, they cannot be used in such a wide range of functionality, which is provided by "white" addresses.

Some ISPs may issue a "gray" address as an IP. Previously, mobile operators sinned with this, now I do not know how things are - I have not taken such tariffs for a long time. Such an address is quite efficient until it comes to network settings - opening ports, setting access to computer files from the outside. The speed is significantly reduced, or the connection is cut off. Be sure to check this point when purchasing a service.

I also came across free DDNS providers / hosting services, which included free provision IP addresses. After registration, you are given an address. The provider disappeared six months later and I was left without an address. By the way, he worked poorly with interruptions. When they finally pulled the cable, I already took the normal tariff.

How to get a white IP address, its pros and cons

There is only one minus - the subscription fee. But not expensive. For a legal entity, of course, services are always more expensive than for an individual. To get a "white" full-fledged static address, you need to analyze the services provided in your place of residence and choose the best offer for you.

The "white" static address issued by the Internet service provider is registered in the router settings. Gray IP is registered in the settings of the network card of a computer or smartphone.

Rostelecom, Teleseti, MTS, Megafon, Beeline - these providers provide the necessary service packages. The cost of the subscription fee will increase for an individual by 150-200 rubles per month. For a legal entity, the fee can be about 4000-6000 rubles, it all depends on its size and the number of connected numbers. Your address is definitely "white" if it is not included in the ranges:

  • from 10.0.0.0 to 10.255.255.255;
  • from 172.16.0.0. at 172.31.255.255;
  • 192.168.0.0. by 192.168.255.255.

How to find the IP address on your computer?

Finding the address is very easy. To begin with, you can find out what type of address we have - static or dynamic. To do this, right-click on the connection icon, open the network connection parameters:

Open the "Network and Sharing Center":

Find "Change adapter parameters", go there:

Go to the "Properties" of the selected network adapter. This adapter must be physical, not virtual:

We find the "IPv4" protocol and go to its properties:

Here is the coveted window. If it is worth "Assign an address automatically" then you definitely have a dynamic address type.

A static, "gray" IP address may look like this if configured:

The line "Default gateway" contains the IP assigned to the router to which your computer is connected. This address range fits 254 computers. The router is usually assigned an address under the number "1" if the settings are done manually. When DHCP is activated, numbers can be assigned automatically .

In order to find out your external IP, go to the Internet and type in Yandex "Find out IP ..."

If you decide to measure the Internet speed, then the external address will also be visible there:

Where can I find the IP address on the router?

If you have a router, you can configure the address given to you on the router. The address of a router is usually written on the back of its case. If you have a modern router purchased from a provider, as a rule, the address as well as the login and password are on the box from it. By the way, the address of the router is an IP address, but this is not a white address, but a gray one. In the browser, we drive in the address, enter the login and password:

In the settings of any router there is always a tab in which the Internet settings are entered. It all depends on the model. But the essence is the same everywhere. This is how the static, "white" (external) address given by the provider in the "settings" looks like:

Internal, "gray", static addresses on the router can also be viewed, but in another section. In different models, the appearance of the menu is different:

What can be done knowing the IP address of someone else's computer?

You should not provide information provided by the provider to outsiders. If your computer and network are configured correctly from a security point of view (firewalls are enabled, password protection is organized on the computer, account settings are made, there is a good domestic paid antivirus), then this will significantly increase security. We have already learned that internal, "gray" addresses are inaccessible from the Internet, if the permissive settings are not made.

If necessary, the address can still be traced along the chain, about which it was said, to establish the location of the computer. It is possible to determine the provider that issued it by the range of the address. There are Internet zones and programs that can provide subscriber anonymity to some extent. Although it is quite difficult to provide permanent complete anonymity in our time, it requires funds and knowledge. System administration within the network is another matter. In addition to the services provided by a static, white address, you can do a lot of useful things:

  • connect remotely to the desktop of the desired computer;
  • organize the exchange of messages (chat) between computers on the network;
  • access shared folders on the selected computer and exchange documents;
  • wake up the computer over the network;
  • Install Windows over the network;
  • Open documents on another computer if you configure access to them;
  • access a shared printer that is connected to the selected computer;
  • get access to network equipment - scanner, printer;
  • check - how many computers are currently on the network and whether there are any extraneous devices.

And many many others.

Every computer connected to the Internet or to a local computer network has an IP address. It can be static or dynamic. What are the features of each of them?

Briefly about IP addresses

Before talking about the differences between static and dynamic IP-addresses, let's take a short theoretical excursion into the field of networking technologies.

An IP address is a unique identifier for a PC within a local area network (or LAN) or global, which is the Internet. It is a sequence of 4 groups of 3-digit digits like "192.192.192.192", where 192 can be any value. This principle of constructing IP addresses is the same for all types of computer networks - LAN, Internet.

The phrase "static IP" or "dynamic IP" is most often used exclusively as a characteristic of a computer or server. That is, you should say "this PC has a static IP". Later in the article, we will consider the differences between IP addresses in this very context - as the most widely recognized.

But there is another approach to using the terms "static" and "dynamic" IP - in order to denote the constancy of the IP address structure. It cannot be called too popular, but it is worth paying attention to. This approach assumes that a static IP is understood as a sequence of 4 groups of 3-digit digits, which, in principle, does not change one digit for a sufficiently long time. In this case, the corresponding sequence may not be connected in any way with any computer and be part, for example, of the software algorithm for generating IP addresses in the network or in the infrastructure of the Internet provider.

Static IP Facts

The main feature static IP address (in the most popular meaning, which we mentioned above) - persistence every time a computer connects to a local network provider or router. In the first case, users or LAN owners, as a rule, enter into an agreement with a communication service provider, according to which a static IP is assigned to a subscriber PC or LAN.

The permanent IP address assigned to the computer by the provider is almost guaranteed to be unique, the only one in the entire global online space. In turn, it is also impossible to operate two computers with the same IP within the same LAN.

In local computer networks, computers with a permanent IP address are usually the majority. This is necessary in order to ensure the stability of the LAN. Often, the servers of Internet providers, to which subscribers connect, also have a static IP address.

The need for a permanent IP issued by an Internet provider on the PC of ordinary users is often associated, for example, with the frequent use of any network service on it - as an option, a gaming one, to which other players connect from time to time.

Also, a static IP from a provider can be useful to improve the security of connections to banking services. Some financial institutions only welcome their clients' ability to connect to systems of the Client-Bank type from computers with a static IP address. In this case, access to the corresponding services from any third-party PCs is practically excluded - since their IP is almost guaranteed to be different. The presence of the correct login, password and even electronic signature of the owner of the bank account by third parties will not play any role.

Dynamic IP Facts

Dynamic IP , in turn, are fickle. They are assigned by the ISP or LAN router for the duration of the communication session between a specific PC and a server.

Of course, in some cases, the same IP can be provided to a computer that connects to the Internet, or a PC that connects to a LAN, several times during different sessions with the server. But any patterns that allow, for example, to calculate what the IP will be the next time you connect, is quite difficult to find here.

The software and hardware algorithms by which a specific IP address is assigned to the user when entering the Internet is known only to the provider. The definition of an IP router within a LAN is sometimes completely random. But many models of corresponding network devices assign IP to local PCs based on their LAN connection order. For example, if the first computer received an IP like 192.168.0.1, then the next one will receive the address 192.168.0.2.

Comparison

So, the main difference between static and dynamic IP is that the first is permanent and does not change when the subscriber reconnects to the provider or to other computers within the local network. The second one changes periodically.

It should be noted that the IP address of a computer (assigned by a provider or local network administrator) may not always coincide with the IP address under which this PC enters the online space - to sites, on social networks, initializing in instant messengers. The fact is that the IP under which the computer is seen by the servers of the corresponding Internet resources can differ from that given by the provider. For example, if the user used a proxy server when connecting to the Internet (on which, in turn, software algorithms for issuing both static and dynamic IP addresses can be applied).

In addition, it is extremely rare that the static IP under which the computer is registered in the local network coincides with the IP issued by the provider when the corresponding LAN is connected to the Internet. It is under the second IP that the PC will be initialized on online resources. At the same time, this IP can be both static and dynamic - depending on the agreement concluded between the owners of the LAN and the communication service provider.

Another noteworthy point: in theory, IP, which was once static for a specific PC, often begins to be used as dynamic - and vice versa. The fact is that both types of IP addresses have exactly the same construction, which, as we noted above, looks like "192.192.192.192", where 192 can be any three-digit number. Static and dynamic IP addresses are completely interchangeable and are technologically identical. The difference between them, therefore, is very small and boils down to only one feature - changeability when reconnecting to a LAN provider or router.

Having determined what is the difference between static and dynamic IP, we will fix its main criteria in the table.

What do they have in common?
Have the same design
The former static IP can start to be used as one of the dynamic ones - and vice versa

Every device that is connected to the Internet has its own identification number, that is, the IP address on the network. With the help of this distribution, computers are able to communicate with each other, transferring information that the user needs. The number of such addresses is limited to 4.3 billion possible mathematical combinations.

What is the difference between dynamic and static ip? Which one is better? Pros and cons of each

There are two methods for assigning an IP address:

1. DHCP (Dynamic Host Control)

2. Static assignment of IP addresses.

What is the difference between dynamic and static ip? Which one is better? Pros and cons of each

The first type is more common in our time, since it implies the automatic assignment of an IP number in the subnet (local network) to which it connects; the host (modem, router, or other computer) is responsible for this. Thanks to this, the computer can receive and send packets to the host (or, conversely, receive them from the host), and the host, in turn, goes to the global network and transmits the necessary packets over the Internet.

The second type of assignment, static, is typically used to support servers. To use such an appointment, you will need to send a special request to the Internet provider, and, possibly, for an additional fee. Unlike dynamic assignment, static IP will not change over time. Otherwise, the principle of operation is identical.

What is the difference between dynamic and static ip? Which one is better? Pros and cons of each

If you sum up the results, then the dynamic assignment has advantages in that it is free, in case of a ban, you can change the IP, but on the other hand, you can just grab the banned IP, there is a possibility of communication disconnects.

A static IP is suitable for those who need a more stable connection, who maintain their own servers, and also, the provider will have to pay for a static address.

IP addresses: dynamics versus static

IP-address (internet protocol address) in the broadest sense - the address of a specific node of a network based on the IP protocol. Simply put, every computer or device connected to the Internet gets a unique IP address, and it looks like a set of four numbers from 0 to 255 - dotted between them. This is the so-called "external" IP address, that is, the one with which you access the Internet. You can find out the IP on specialized sites - for example, here https://2ip.ru/).

In addition to the external IP address, there is also such a thing as a local IP, that is, an address within the network of a certain provider. The fact is that there is a shortage of external IP addresses in the world, and providers often give the same IP address to several clients. But at the same time, within the network of the provider itself, each computer receives a special local IP that is not used to access the global web.

An external IP address can be static, that is, constant, and dynamic - it changes every time you reconnect to the Network, restart the router, and so on. Many users, noticing that their IP address has changed, begin to ask questions: is everything all right, has their computer been hacked, and so on. Now we will try to figure out what are the advantages and disadvantages of dynamic and static IP and how to get the type of address that you need.

Why does IP change?

Some ISPs provide dynamic IP addresses quite officially. The point is that the number of unique IP addresses available to a provider may be less than the number of its clients. But since often not all users connect to the Internet at the same time, sometimes providers act as follows: when connecting, the user is given one of the IP addresses that are free for that minute, and at the end of the access session, this IP is returned to the list of available for subscribers. However, in our time it is no longer so relevant, because most people use routers and they are turned on 24 hours a day.

Dynamic versus static IP addresses: advantages and disadvantages

Dynamic IP address

It is generally accepted that dynamic IP addresses are much safer for novice users. For example, if someone starts hacking your network node to gain access to your computer, after such an elementary procedure as restarting the router, the attacker will have to re-learn your IP address and start hacking from scratch.

Sometimes constantly changing the IP address is useful for work. For example, if you are engaged in SMM, hidden PR or other activities related to communication on sites under different names, then it will look suspicious and implausible with the same IP address. Dynamic IP change will come in handy for you.

In some cases, a so-called "ban" can be applied on forums and conferences, that is, a ban on access for a specific participant. Sometimes a more severe restriction is applied - blocking a specific IP. If you fall under such sanctions, then the dynamic change of the IP-address will allow you to freely read the information on your favorite resource and even register there under a new name in order to continue communication. Cases when all IPs of a particular provider are blocked are extremely rare.

Also, dynamic IP is convenient when you work with free file hosting services. Often, restrictions are imposed on them - for example, you can download no more than 1 file in 3-6 hours from one IP. After downloading the first document, you just need to restart the router, and you can immediately start downloading the second one.

Static IP address

A static IP address lacks these benefits, but has different benefits. For example, when authorizing on the websites of Internet banks and other resources that require maximum protection of information, it is possible to bind the login (account) to a specific IP. And even if third parties find out your password, they are unlikely to be able to access secret data, since this will only be possible from your IP. But keep in mind that if you change your provider, you will lose this IP address. Also, you will not be able to access your account on the site from another location.

Sometimes it becomes necessary to access your home or some other computer remotely - for this, special software is used: for example, TeamViewer or Remote Administrator. With the help of such "software", knowing the IP-address and a special password, it will be possible to work with the computer remotely, to see the desktop and all the contents. The main thing is that the program is installed on both computers, including the one to which you want to access. But this is possible only if the computer is assigned a predefined static IP. In the case of a dynamic IP address, even an elementary disconnection will make it impossible to get remote access.

Also, a static IP is necessary if you want to keep a game server on your own computer or be a hoster for your site. In this case, of course, the IP must be constant, otherwise users will constantly lose access to your resource.

How to change dynamic IP to static and vice versa

If your ISP provides a static IP address, and for some reason you want to change or hide it, this is not a problem. You can use a special browser utility (https://2ip.ru/article/browserplugins) or an anonymizer (https://2ip.io/anonim/), which allows you to get a different IP address at any second. So, for example, you will go to the site where your IP was blocked. Alternatively, in the properties of the network connection, open the settings of the TCP / IP version 4/6 protocol (depending on which one you are using) and check the box next to the "Obtain an IP address automatically" item. In this case, with each new connection to the Network, your node will receive a new address.

If, on the contrary, you need a static IP address, and your ISP provides a dynamic one, you can solve this problem as well. You need to go to the settings of your network connection, check the box next to "Use the following IP address" and manually register a specific IP. Of course, it must belong to the pool of addresses available specifically to your ISP. If the address is already occupied by someone, you will need to change the IP until you find a free one.

In some cases, it is easier to use the DynDNS service (https://www.noip.com). It allows you to get a subdomain and bind it to a specific network device, including your computer, which does not have a permanent address. This will make it possible to get to your FTP server, website or other resource from the outside at any second, since even with a dynamic change of the real IP address, thanks to the service, a permanent address for access will be saved.

An IP address is called dynamic if it is assigned automatically when the device connects to the network and is used for a limited period of time, usually before the connection session ends. Static IP addresses are fixed addresses that can only be changed manually. They are used in cases where the administrator does not want the IP information to change, for example, for internal servers on the local network, servers connected to the Internet and routers. Using static IP addressing, you assign an address and it remains unchanged. Other machines know that you are always available at a specific IP address and can contact you at any time using that address. Many Internet users confuse the concepts of "gray" IP-address and dynamic, mistakenly believing that all addresses allocated by the ISP dynamically are "gray", and fixed addresses (assigned statically) are "white". This is fundamentally wrong. Any address, both "gray" and "white", can be dynamic or static.

dynamic IP changes when reconnecting, but static does not ... I'm pumping from rapid and I'd rather have a dynamic ... re-connecting the net and avoiding the link timeout ...

Elvis Ablyazizov Master (1736) 11 years ago

To do this, it is enough to have a software that allows you to work through a proxy server) Well, or a couple of addresses like this: http://anonymizer.nntime.com

The "goodness" of this or that IP lies in the tasks that you use. For torrents, for remote control of a computer (via RAdmin, for example), for some other tasks, a static IP is needed so that the machine is recognizable from the network at any time. Dynamic IP is good, as already mentioned, for downloading from Rapida. I downloaded the archive volume, reconnected (with a new IP assigned) - download a new one without waiting for an hour. My wife constantly uses torrents, so she has to pay extra monthly (a little) for a static IP. I don’t need torrents, so I’m content with a free dynamic IP.

If, in addition, in the settings your wife puts a lower hyphen in front of the address, her rating will not be taken into account, ATP. for answer ;)

Elvis Ablyazizov Master (1736) 11 years ago

In fact, dear, your wife is doing nonsense! Well, why does she need a static IP on torrents? After all, sites of this kind take into account statistics not by your IP but by the pass-key that is assigned during registration and assigned to your account! some "well-wishers" who see on the local network stupidly laid out torrent files, in addition to the basic information downloaded and posted for everyone to see, try to spy on the pass-key from there as soon as possible and use it for personal gain) in such a way when they download something from a torrent, the traffic is considered not to him, but to the account to which this key is assigned.
