Class A – the binary number begins with 0 meaning the decimal number can be anywhere from 1 to 126.

Class B – the binary number begins with 10 meaning the decimal number can be anywhere from 128 to 191.

Subnet Masking – this is the process of using a mask to determine what subnet an IP address belongs to. Each IP address consists of 2 parts: the network address and the host address.
