[Feature Request] Core Networks DynDNS

Hi,

It would be nice if you could add support for the German DynDNS provider Core Networks.
They’re DynDNS2 compatible (according to their docs).

Public docs: https://www.core-networks.de/faq/dyndns-client.html
Example request URL: https://dyndns.core-networks.de/?hostname=<domain>&myip=<ipaddr>,<ip6addr>

Regards

Hey,

I can recommend that you have a look at the last few patches in the ddns repository:

https://git.ipfire.org/?p=ddns.git;a=summary

There are plenty of examples on how to add support for new providers.
