Why is IP changing?
IP-address is a unique identifier of a computer within a computer network built using the same protocol. The global Internet is functioning on IP protocols. At the same time, the Internet is a plexus of networks, the internal connection of which is sometimes based on other protocols.
The IP address of a computer can also be its identifier within the entire Internet. Such an address is called an external address. However, this is not always the case. Many networks have a single external IP address that is used to connect all computers on the network to the Internet, and responses from the Internet, reaching the internal network, are distributed according to internal addresses.
Today in the world there is a situation of shortage of external IP-addresses. The number of devices with access to the global network is approaching the maximum possible number of IP addresses.
Under these conditions, many providers that provide computers with IP addresses go to the next “trick”.Computers that connect to such a provider do not have a permanent address, otherwise called a static IP address. Instead, dynamic technology is used. Here is an explanation of why the IP address is changing.
The dynamic connection is that when you connect your computer to the network, it is automatically assigned one of the available IP addresses. The computer shuts down - the used address is released and can be assigned to another computer. When you turn on the computer again, you will most likely find that the IP has changed because it was chosen randomly from among the available addresses.
Now the reason why IP is changing is well known. Let's talk about how and why to deal with it. Such technology is sometimes inconvenient because some Internet services are bound to the IP of their clients. The next time you change IP, you have to reconfigure these services. The way out of this situation is to rent a static IP address, which rigidly binds the MAC address (the unique address of the network card issued at the manufacturing plant) to an external IP. This service is provided by almost all providers.To connect it, contact your Internet provider.
In addition, the owners of some sites sometimes block users from accessing their resources by IP address. This means that access can be lost not only by the offender, who was denied access to the site, but also by an innocent user, who, by coincidence, was assigned a blocked IP address.
