If your Internet Service Provider (ISP) gave 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 allows you to register your domain to their IP address, and forwards 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.

Your NETGEAR WNR2000 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 specify in the router. Then, whenever your ISP-assigned IP address changes, your router automatically contacts the Dynamic DNS service provider, logs in to your account, and registers your new IP address. If your host name is hostname, for example, you can reach your NETGEAR WNR2000router at hostname.dyndns.org.

Select Dynamic DNS under Advanced in the main menu. The Dynamic DNS screen displays.

To configure for a Dynamic DNS service:

1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. For example, for DynDNS.org, select www.dynDNS.org.

2. Select the Use a Dynamic DNS Service check box.

3. Select the name of your Dynamic DNS service provider.

4. Enter the host name (or domain name) that your Dynamic DNS service provider gave you.

5. Enter the user name for your Dynamic DNS account. This is the name that you use to log in to your account, not your host name.

6. Enter the password (or key) for your Dynamic DNS account.

7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use Wildcards check box to activate this feature.

For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.

8. Click Apply to save your configuration.
