DDNS
Dynamic Domain Name System. An algorithm that allows the use of dynamic IP address for
hosting Internet Server. A DDNS service provides each user account with a domain name.
A router with DDNS capability has a built-in DDNS client that updates the IP address
information to DDNS service provider whenever there is a change. Therefore, users can
build website or other Internet servers even if they don't have fixed IP connection.
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.
