An IP address is a unique address of a computer on an IP network that is used to move data between nodes. In this case, delivery to the addressee is not guaranteed. Basically, the IP address is somewhat similar to your home mailing address.
As known. The IP address of the fourth version, which is currently in use, consists of 4 groups of decimal numbers containing 3 digital characters each with a value from 0 to 255. The groups are separated by periods.
The agreement on the use of IP addresses contains information on dividing them into dynamic and static. The difference lies in whether the computer has a constant address or changes with every connection.
The answer to the question about the reasons for changing the IP address is simple. Each provider is allocated a certain range of addresses. When you go online, your computer receives an address. The number of electronic computers connected to the Internet is growing every year. Naturally, assigning a separate IP address to a separate machine is simply unrealistic. The existing number of addresses is simply not enough for everyone.
For this reason, a decision was made that suited many. The IP address was given to the computer only at the moment of connecting to the network. That is, when a computer or modem sends a request to access the network. All IP addresses that are not currently in use are in reserve. If you restart your modem, disconnect or restart your computer, you will be assigned a new IP address. At the same time, information on who, when and what IP-address was issued must be kept by the provider in case of a request from law enforcement agencies. The allocation of the same address occurs "blindly", it is impossible to guess which one you will get next time. When
Thus, there can be only one explanation: you have a dynamic IP address.
Remember: usually for an additional fee, you can connect a service from your provider, according to which your IP address will become static, i.e. will not change.
Both systems have their pros and cons. With dynamic, you can bypass the ban, as well as download more files from free file hosting services. With a static one, you can work in programs that need a rigid binding to the address, as well as continue downloading if the connection is broken on some services.
