Dynamic DNS

The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing

users whose ISP does not assign them a static IP address to use a domain name. This is especially

useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may

use your domain name, rather than having to use your dynamic IP address, which changes fromtime

to time. This dynamic IP address is the WAN IP address of the router, which is assigned to you by

your ISP.

You will first need to register and establish an account with the Dynamic DNS provider using their

website, for example

http://www.dyndns.org/

downstream
