IP address
Internet Protocol address
The address of a host (computer) on the Internet,
consisting of four numbers, each from 0 to 255,

address consists of a network ID that identifies the
particular network the host belongs to, and a host ID
uniquely identifying the host itself on that network. A

host ID. Because IP addresses are difficult to
remember, they usually have an associated domain
name that can be specified instead. See domain name,
network mask.
