Subnet Mask

The subnet mask is used in conjunction with the network address to determine which part of the address is the network address and which part is the host address.

A subnet mask may look like 255.255.255.0 which means the first 3 bytes are part of the network and the last byte is the address of the host on the subnet.

Another way to write the same network mask as above is /24 which means the 24 first bits (8 bits * 3 bytes) are part of the network.
