IP address
Internet Protocol address
The address of a host (computer) on the Internet,
consisting of four numbers, each from 0 to 255, separated
by periods, e.g., 209.191.4.240. An IP 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 network mask is used to define
the network ID and the host ID. Because IP addresses
are difcult to remember, they usually have an associated
domain name that can be specified instead. See also
domain name, network mask.
