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/
