The length of the network identifier in the Class C IP address is 21 bits, the length of the host identification is 8 bits.

Class C IP addresses use the first 24 digits to identify the network number, of which the first three digits are specified as "110", and 8 digits identify the host number. In this way, the first segment of the Class C address has a value of "110000~10111" , after conversion to decimal, it is 192~223. The first segment, the second segment, and the third segment together represent the network number. The last segment identifies the host number on the network. Its address range is "192.0.0.0~223.255 .259.255".

Class C addresses are suitable for small networks such as campus networks and office networks. Each Class C network can have up to 254 computers. This type of address has the largest number of addresses among all address types. However, this type of network allows the least number of computers to be connected. This type of IP address can be assigned to anyone in need. Among them, 192.168.0.0~192.168.255.255 is the private address segment of the enterprise LAN.
