IP Address Classes
IP addresses are divided into 5 groups
Class A
Class B
Class C
Class D
Class E
Classes D and E are reserved for multicast and experimental purposes. Each class has a valid range of IP addresses.
IPv4 addresses are divided into two parts
Network ID
Host ID
The class of an IP address is used to determine the number of bits used for the Network ID, and the Host ID, which ultimately determines the number of hosts on a network. It is the job of the network administrator to assign host IP addresses within a network.
