Describe the IP Address
Structure

An IP address occupies 32 bits and includes both a network ID and a
host ID.
A

host

refers to either a workstation or a server. A host is also referred to
as a node or station.
Routers locate hosts on the Internet based on their assigned IP
addresses.
The IP address of a host consists of four bytes divided into two parts:

■

A network address (varying from one to three bytes)

■

A node or station address (varying from one to three bytes)
