Ipv6 change request overrides ipv4 and vise versa

My openwrt is configured to use desec as dyndns like this:

So there are two processes that update ipv4 and ipv6 separately making requests:

https://update.dedyn.io/?username=&password=&hostname=myhost&myipv4=127.0.0.1
https://update.dedyn.io/?username=&password=&hostname=myhost&myipv6=::1

And it seems like request to update ipv6 wipes ipv4 and request to update ipv4 wipes ipv6.

@peterthomassen , I would love to contribute, but given I have too many side-project at this time I’m afraid I won’t produce good enough code. I’ll try to find time later, though!

We only support this quirky interface because it so many routers support it out-of-the-box. In your case, you seem to have far-reaching control over which software your router is running. Why not use the REST API in this case? It has much better behavior and allows for fine-grained control over how you want to update the DNS information.

Anyways, I think the ipv6=preserve (and ipv4=preserve) option could be a valuable extension of the quirky update API that we are currently providing.
