IPv4 Address

An IP Class is used to categorize and classify an IP address based on the IP address’ first octet’s value. There are 5 IP Classes (A, B, C, D, and E) and each IP Class has a specific range of IP addresses that determine the number of devices and networks you can have in your network. Class A, B and C are primarily used in general networks, however, Class D and E are used for multicast and experimental purposes.
