Internal Class A, B & C

Class A, B, and C are the three different types of internal networks that are used to connect devices and applications. They are defined by the number of bits used for addressing devices on a network, called IP addresses.

Class A networks use the first 8 bits for the network address and the remaining 24 bits for the host address. This allows for a large number of devices to be connected, with a network address range of 10.0.0.0 to 10.255.255.255.

Class B networks use the first 16 bits for the network address and the remaining 16 bits for the host address. This allows for a moderate number of devices to be connected, with a network address range of 172.16.0.0 to 172.31.255.255.

Class C networks use the first 24 bits for the network address and the remaining 8 bits for the host address. This allows for a smaller number of devices to be connected, with a network address range of 192.168.0.0 to 192.168.255.255.

In simple terms, the difference between Class A, B, and C networks is the number of devices that can be connected and the range of IP addresses that can be used for each network. You're most likely to see 192.168.1.0 on your network at home for example.
