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 difficult to remember, they usually have an
associated domain name that can be specified instead. See also
domain name, network mask.
ISP Internet Service Provider
A company that provides Internet access to its customers,
usually for a fee.
LAN Local Area Network
A network limited to a small geographic area, such as a home,
office, or small building.
LED Light Emitting Diode
An electronic light-emitting device. The indicator lights on the
front of the Ethernet Modem Router are LEDs.
MAC address Media Access Control address
The permanent hardware address of a device, assigned by its
manufacturer. MAC addresses are expressed as six pairs of
characters.
mask See network mask.
Mbps Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
microfilter In splitterless deployments, a microfilter is a device that removes
the data frequencies in the DSL signal, so that telephone users
do not experience interference (noise) from the data signals.
Microfilter types include in-line (installs between phone and jack)
and wall-mount (telephone jack with built-in microfilter). See also
splitterless.
NAT Network Address Translation
A service performed by many routers that translates your
network’s publicly known IP address into a private IP address for
each computer on your LAN. Only your router and your LAN
know these addresses; the outside world sees only the public IP
address when talking to a computer on your LAN.
NAT rule A defined method for translating between public and private IP
addresses on your LAN.
