The Subnet Mask
The Subnet Mask is another 32-bit binary number that is used to 'mask' certain bits of the IP Address. This
provides a method of extending the number of network options for a given IP Address. It works by allowing part
of the host identifier to be used as a 'subnet identifier'.
It is important that you set the correct value for the Subnet Mask. The basic values depend on the class of IP
Address being used:
Class Name Subnet Mask
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0
