Netmask setting
The ``netmask'' strips the network ID from the
IP address, leaving
only the host ID. Each netmask consists of binary ones
(decimal 255) to mask the network ID and
binary zeroes (decimal 0) to retain the host ID of the
IP address. For example,
the default netmask setting for a Class B address is 255.255.0.0.
NOTE:
Always use the default netmask that the installation program prompts you for
unless you are creating a subnet (a logical division of a physical network).
If you create a subnet, also mask the portion of the address that indicates
the subnet. For example, the netmask for a machine on a Class B subnet is
255.255.255.0. For more information, see
``Creating subnets''.
