What is an IP Address?
■
The IP address is an identification number allocated to computers and other devices connected
to an IP network. An IP address is an address for use on a network. There are two types of IP
address: IPv4 and IPv6.

IPv4 address
The IPv4 address consists of four fields, such as "192.168.0.113". The first three fields
(192.168.0) are fixed, and the last one (113) is variable.
