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.
