Why the ip is changing
As is well known. IP address of the fourth version, which is now used consists of 4 groups of decimal numbers each containing 3 numeric characters from 0 to 255. Groups separated by dots.

The agreement on the use of IP addresses provides information about the division into dynamic and static. The difference lies in the fact that the permanent address for the computer or is changing each time you connect.

The answer to the question on the reasons for changing IP addresses is simple. Each provider is allocated a specific range of addresses. When access to the network, your computer gets the address. The number of computers connected to the Internet, grows every year. Naturally, to secure a separate IP address for separate machine is simply unrealistic. The existing number of addresses is simply not enough at all.
