IP Addressing Basics
... The default subnet mask uses all binary ones, decimal 255, to mask the first 8 bits of the Class A address. The default subnet mask helps routers and hosts determine if the destination host is on this network or another one; there are only 126 Class A networks, the remaining 24 bits, or 3 octets, ca ...
