Why does IP change?
IP address - a unique identifier of the computer in theThe limits of a computer network, built on the same protocol. On the IP protocols, the global Internet is functioning. At the same time, the Internet is a network of networks, the internal connection of which is sometimes based on other protocols.
The IP address of the computer can also beidentifier within the entire Internet. This address is called the external address. However, this is not always the case. Many networks have a single external IP address 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 deficiency of external IP-addresses. The number of devices with access to the Global Network is approaching the maximum possible number of IP addresses.
In these conditions, many providers whogive computers IP addresses, go to the next "trick." Computers that connect such a provider do not have a permanent address, otherwise known as a static IP address. Instead, dynamic technology is used. Here is an explanation of why the IP address is changing.
Dynamic connection is thatWhen you connect your computer to a network, it is automatically assigned one of the available IP addresses. The computer shuts down - the address used 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 known. Let's talk about how and why to fight it. This technology is sometimes inconvenient in that some Internet services are tied to the IP of their customers. When you change the IP again, you must reconfigure these services. The way out of this situation is to lease a static IP address that rigidly binds the MAC address (the unique address of the network card issued to it at the manufacturing plant) to the external IP. This service is provided by almost all providers. To connect it, contact your Internet provider.
In addition, the owners of some sites sometimesblock users access to their own resources by IP-address. And this means that access can be lost not only to the violator, who was denied access to the site, but also to an innocent user, who, by coincidence, was assigned a blocked IP address by dynamics.
