Cool. I am currently using the OVH dyndns option and it is a bit annoying that you have to update each sub-domain individually and can’t just tell OVH to update all subdomains to the same new IP via a wildcard.
Is that something your script could do?
Also it seems like the OVH dyndns API currently only does either IPv4 or IPv6 but not both the same time.
Edit: Ah I see you plan to allow creating sub-domains through it. I guess that would indirectly solve my issue as well.
It does solve my problem in the sense that right now I need to configure each subdomain individually both in the OVH web-ui and then a second time on my firewall for the dyndns update. With a few dozen subdomains that is both annoying and easy to mess up accidentally.
If I can manage everything from env parameters in a single location that saves me a lot of hassle.
