The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other
server behind the Router.
Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers,
DynDNS.org or TZO.com. If you do not want to use this feature, keep the default setting, Disable.
