Fallback Subnet Mask:
Subnet mask is made for the purpose to get more network addresses
because any one IP device in a network must own its IP address,
composed of Network address and Host address, otherwise it can’t
communicate with other devices on the network. But unfortunately, the
network classes A, B, and C are all too large to fit for almost all networks,
hence, subnet mask is introduced to solve this problem. Subnet mask
uses some bits from host address and makes an IP address looked
Network address, Subnet mask number and host address. It is shown in
the following figure. This reduces the total IP number of a network able to
support, by the amount of 2 to power of the bit number of subnet number
(2^(bit number of subnet number)).
