IP Addresses and Subnetting
This appendix introduces IP addresses and subnet masks.
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to
communicate across the network. These networking devices are also known as
hosts.
Subnet masks determine the maximum number of possible hosts on a network.
You can also use subnet masks to divide one network into multiple sub-networks.
Introduction to IP Addresses
One part of the IP address is the network number, and the other part is the host
ID. In the same way that houses on a street share a common street name, the
hosts on a network share a common network number. Similarly, as each house
has its own house number, each host on the network has its own unique
identifying number - the host ID. Routers use the network number to send packets
to the correct network, while the host ID determines to which host on the network
the packets are delivered.
Structure
An IP address is made up of four parts, written in dotted decimal notation (for
example, 192.168.1.1). Each of these four parts is known as an octet. An octet is
an eight-digit binary number (for example 11000000, which is 192 in decimal
notation).
Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or
0 to 255 in decimal.
