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 from time 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/
