native dyndns support #46

Closed stapelberg closed 4 years ago

stapelberg commented 4 years ago

The https://github.com/libdns libraries¹ provide a uniform interface for updating DNS records across providers.

We could use these to implement dyndns: take the public IPv4 address of uplink0 and set it as an A record in the configured provider(s).

Personally, I use cloudflare for DNS, and have a little program which does these updates.

① Not entirely sure how ready they are. They come with a disclaimer.

Just switched from my custom dyndns updater to the built-in dyndns, and it seems to work well!

Calling this done. Follow-up improvements can be tracked in a separate issue.

If you’re curious: @mdlayher and I built this feature on our twitch streams. Find the recording at:
