IP Addressing
An IP (Internet Protocol) address is a unique set of numbers assigned to a device
on a network to uniquely identify that device (by its IP address).
An IP address is a unique number composed of four octets, with each octet
An IP address is a unique number composed of four octets, with each octet
separated by a dot. This notation style is called dotted decimal notation.
Each IP address can be broken down into two parts, as shown in the example
Each IP address can be broken down into two parts, as shown in the example
below:
Example: 128.121.188.201
The first two octets are the network ID: 128.121
The second two octets are the host ID: 188.201
The second two octets are the host ID: 188.201
• Network ID - In this example, the 128.121 portion of the IP address
defines the network that a host belongs to, and is equivalent to a street
name in a mailing address.
• Host ID - The 188.201 portion of the IP address specifies a unique number
assigned to the host on the network, and is equivalent to a house number in
a mailing address.
IP Address Classes
IP addresses are assigned to classes according the schedule shown in
Figure A-4. IP address classes are assigned as follows:
