IP
Internet Protocol. IP is a layer 3 network protocol that
is the standard for sending data through a network. IP
is part of the TCP/IP set of protocols that describe the
routing of packets to addressed devices. An IP address
consists of 32 bits divided into two or three fields: a
network number and a host number or a network
number, a subnet number, and a host number.

is written as four octets separated with periods
(full-stops), and is made up of a network section, an
optional subnet section and a host section.
