Hi,

I hope this is the correct way to submit this patch.

https://www.domaindiscount24.com/ has its own ddns service runnning,
which (for me) gets rid of the necessity of having to use an extra
service for that.

I tested the following patch on my system at home, and attached it to
this mail.

I started my quest at the community forum:
