  • Copy the URL right from Dynamisches DNS Server:
  • Copy the Authhash of the respective domain.

Use the current dynamic DNS server from the customer center instead of DYNAMIC_DNS_SERVER and the current Authhash from the customer center instead of AUTHHASH.

  • Confirm with ENTER.
  • In case you want to use a customized IP please use the following pattern:
 curl --insecure "DYNAMIC_DNS_SERVER/?ah=AUTHHASH&ip=YOUR_IP"

Use the current dynamic DNS server from the customer center instead of DYNAMIC_DNS_SERVER and the current Authhash from the customer center as well instead of AUTHHASH. Use the dsired IP instead of YOUR_IP.

If everything has been entered correctly you will receive a message from the dynamic DNS server in the following format:

 OK Domain IP = CURRENT_IP

Where CURRENT_IP represents your current IP.

The update can also be conducted via a cron-job of course.
