Configure dynamic DNS on your modem

Dynamic DNS (DDNS) associates the WAN IP address of your router with a hostname, and automatically updates DNS servers upon WAN IP address change. DDNS is a separate service provided by http://www.dyndns.com.
NOTE:  This article applies to newer CenturyLink modems. Depending on your particular model, you may see slight differences in the features or layout of your modem's user interface.
Modem Advanced Step 1-4

1.  Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.

2.  Open a web browser and type http://192.168.0.1 into the web address field.

3.  Log in to the modem's online user interface (Modem GUI) using your Administrator Username and Administrator Password. Unless you have changed the default settings, you can find this information on the modem's sticker. Note that these are different from your wireless SSID and security key.

4.  Select "Advanced Setup."

5.  Select "Dynamic DNS" in the left sidebar. This menu option may appear in the WAN Settings section or in the IP Addressing section, depending on your particular model.

6.  Follow the steps to edit the settings:

Step 1:  Enable/Disable the dynamic DNS state.

Step 2:  Enter your www.dyndns.com username and password (this must be previously set up).

Step 3:  Enter the dynamic DNS host name.

Step 4:  Click "Apply" to save your changes.
