DDNS

Figure 7-44

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 serv- er 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.

DDNS Service The DDNS feature is disabled by default. To enable this fea- ture, select your DDNS service provider, DynDNS.org or TZO.com, from the drop-down menu.

The features available on the DDNS screen will vary, depending on which DDNS service provider you use.
