An IP address refers to an Internet Protocol address, also known as an Internet Protocol address. All hosts on the same physical network use the same network ID, and a host on the network has a corresponding host ID.

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.
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, classes A, B, and C3 (as shown in the figure below) are uniformly allocated globally by InternetNIC, and classes D and E are special addresses.
