Extended information:

Internet Protocol Address (English: Internet Protocol Address, also translated as Internet Protocol Address), abbreviated as IP Address. The IP address is a unified address format provided by the IP protocol. It assigns a logical address to each network and each host on the Internet to shield the differences in physical addresses.

Every host (Host) on the Internet has a unique IP address. The IP protocol uses this address to transfer information between hosts, which is the basis for the Internet to run. The length of the IP address is 32 bits (a total of 2^32 IP addresses), divided into 4 segments, each segment is 8 bits, expressed in decimal numbers, each segment ranges from 0 to 255, and segments are separated by periods. .

For example 159.226.1.1. The IP address can be regarded as two parts: the network identification number and the host identification number. Therefore, the IP address can be divided into two parts, one part is the network address and the other part is the host address. IP addresses are divided into five categories: A, B, C, D, and E. Their applicable types are: large networks; medium-sized networks; small networks; multi-purpose addresses; and backup. The two most commonly used ones are B and C.
