IP Address and Networ

rnet Protocol. An

address

consists of a series of four

ich identifies a single, unique

Internet computer host in an IP network. Example: 192.168.2.1. It consists of 2 portions: the
IP network address, and the host identifier.

r cascaded binary numbers separated by “.”:

bbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1.

network mask is also a 32-bit binary pattern, and consists of consecutive leading 1’s

llowed by consecutive trailing 0’s, such as:

1111111.11111111.11111111.00000000. Therefore sometimes a network mask can also

t ID.

or example, if the IP address for a device is, in its binary form,

IP

The IP address is a 32-bit binary pattern, which can be represented as four cascaded
decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything
from 000 to 255, or as fou

1
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 network mask become part of the IP network address, and the
remaining bits correspond to the hos

11111111.11111111.11110000.00000000
It means the device’s network address is

routers to route IP packets to their destination.


ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP
address for the Internet router located at the ISP's office.
