For example, if the IP address for a device is, in its binary form,11011001.10110000.
10010000.00000111, and if its network mask is, 11111111.11111111.11110000.00000000
It means the device's network address is 11011001.10110000.10010000.00000000, and its host ID
is, 00000000.00000000.00000000.00000111. This is a convenient and efficient method for routers
