WPNT834 Manual: Using a Dynamic DNS Service

If your network has 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.


	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 Internet.

The router contains a client that can connect to many popular dynamic DNS services. You can select one of these services and obtain an account with them. Then, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.

From the main menu of the browser interface, under Advanced, click on Dynamic DNS.

Register for an account with one of the dynamic DNS service providers whose names appear in the Select Service Provider box. For example, for dyndns.org, go to www.dyndns.org.

Select the Use a Dynamic DNS Service check box.

Select the name of your dynamic DNS Service Provider.

Type the Host Name (or domain name) that your dynamic DNS service provider gave you.

Type the User Name for your dynamic DNS account.

Type the Password (or key) for your dynamic DNS account.

If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may select the Use wildcards check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.

Click Apply to save your configuration.
