How to configure dynamic DNS on your modem

Dynamic DNS (DDNS) links your router's WAN IP address with a hostname, and automatically updates DNS servers when the WAN IP address changes. CenturyLink does not provide DDNS. This outside service has to be set up with a third-party provider

Note:  Your modem settings may appear slightly different from the images below, but the steps will be the same.

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.
