The ip address is a 32-bit binary value used to mark the address of each computer in TCP/IP communication protocol. We usually use the dot decimal representation, such as 192.168.0.5.Each IP address can be divided into two parts. That is, the Network part and host part: the network number indicates the network segment number to which it belongs, and the host number indicates the address number of the host in the network segment. According to the size of the network, IP addresses can be divided i
