The above addresses are invalid because the network identifier for each address
is not the same even though each IP address is unique.

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.
