Home >Common Problem >What identification code does the IP address include?
Each IP address includes two identification codes (ID), namely network ID and host ID. All hosts on the same physical network use the same network ID. A host on the network (including workstations, servers, routers, etc.) on the network has a host ID corresponding to it.

IP address (Internet Protocol Address) refers to the Internet Protocol address, also translated as Internet Protocol 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.
IP address addressing method
When the Internet was originally designed, in order to facilitate addressing and hierarchically construct the network, each IP address includes Two identification codes (ID), namely network ID and host ID. All hosts on the same physical network use the same network ID. A host on the network (including workstations, servers, routers, etc.) on the network has a host ID corresponding to it. The Internet Committee has defined 5 IP address types to suit networks of different capacities, namely Class A ~ Class E.
Among them, categories A, B, and C3 (table below) are uniformly allocated globally by InternetNIC, and categories D and E are special addresses.
