To use DynDNS a DNS API user MUST exist. To do that follow the guide Create User in Customer Portal!

For all domain customers we offer a DynDNS service which communicates with the Servercow nameservers via the Servercow DNS API.

In the following article you will learn how to connect your FRITZ!Box with the DynDNS API of Servercow to use the DynDNS service.

  1. Open your FRITZ!Box in the browser and log in (default via fritz.box or 192.168.178.1).
  2. Log in with your FRITZ!Box access data.
  3. Switch to the Internet tab --> Permit Access. FRITZ!Box Start Page. Internet dropdown expanded, Permit Access highlighted

  4. In the menu Permit Access select the tab DynDNS. Now activate the checkbox at Use DynDNS Please enter the following into the fields:

    DynDNS Options Content

    This example photo was taken with the update URL from the case IPv6 only, therefore the IPv4 status is unknown and only the IPv6 status is registered.
