DHCP
Dynamic Hosting Configuration Protocol. A protocol that enables a server to dynamically assign IP
addresses. When DHCP is used, whenever a computer logs onto the network, it automatically gets
an IP address assigned to it by DHCP server. A DHCP server can either be a designated PC on the
network or another network device, such as a router.
DMZ
Demilitarized Zone. When a router opens a DMZ port to an internal network device, it opens all the
TCP/UDP service ports to this particular device. The feature is used commonly for setting up H.323
VoIP or Multi-Media servers.
DNS
A program that translates URLs to IP addresses by accessing a database maintained on a collection
of Internet servers.

attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols.
