ARP Address Resolution Protocol A protocol to find the physical
address (e.g. MAC address) of a
device on a local area network that

analogue telephone to VoIP.
DHCP Dynamic Host Control

automatically from a DHCP Server.

for local area networks. Common
variants are

100 Base-T – 100 Mbps over UTP

IP runs on many types of media
(Twisted pair, fibre, WiFi, etc.)
An IP address that is unique in the
world (or at least unique in a
customer’s wide area network) is
used to identify devices.
The IP address is different to the
LAN address, which need not be
unique across a WAN (although
paradoxically it is in the case of an
Ethernet MAC address).
LAN Local Area Network A network covering a small physical
area.
NAT Network Address Translator A device that is interposed between
a private network and the Internet,
that translates private IP addresses
on the private network, to one or
several public IP addresses on the
Internet.
