Using a Dynamic DNS Service
If your Internet Service Provider (ISP) gives you a permanently assigned IP address, you can
register a domain name and have that name linked with your IP address by public Domain Name
Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you do
not know in advance what your IP address will be, and the address can change frequently. In this
case, you can use a commercial dynamic DNS service, which will allow you to register your
domain to their IP address, and will forward traffic directed at your domain to your frequently
changing IP address.
Your router contains a client that can connect to the dynamic DNS service provided by
DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host
name, which you will configure in the router. Then, whenever your ISP-assigned IP address
changes, your router will automatically contact the dynamic DNS service provider, log in to your
account, and register your new IP address. If your host name is hostname, you will be able to reach
your router at hostname.dyndns.org.
From the main menu of the browser interface, under Advanced, click on Dynamic DNS to view
the Dynamic DNS menu.
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the
dynamic DNS service will not work because private addresses are not routed on the
