A network mask is also a
1's followed by consecu
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can
also be described simply as "x" number of leading 1's.
When both are represented side by side in their binary forms, all bits in the IP address
that correspond to 1's in the netwo
and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its bin
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 to route IP packets to their destination.

hardware address of a device connected to a network. MAC address is a unique

of data that correspond to the Manufacturer ID (unique for each manufacturer), plus 3
bytes that are often used as the product's serial number.
