DDNS SETUP
DDNS (Dynamic Domain Name Service) allows an ―internet domain name‖ to be assigned to a computer/router which has
a dynamic IP address. This makes it possible for other internet devices to connect to the computer/router without needing
to trace the changing IP addresses themselves. To enable DDNS, you will first need to sign up for DDNS services from
DynDNS.org, TZO.com or ZoneEdit.com.
DDNS is useful when combined with the virtual server feature. It allows other internet users to connect to your virtual
server by using a domain name, rather than an IP address. The DDNS service helps users to locate the right IP address by
the domain name.
For example, you wish to set up a personal web server. However, you obtain a different IP address from your ISP every
time you connect to the internet. The dynamic IP address you have will cause difficulty for other internet users to find your
web server. In this case, you will need to enable DDNS, so other users can connect to you through a fixed domain name to
disregard the potential varying IP addresses behind the server.
