What's the feature?

Some routers, such as Unifi, have the option to specify a custom URL to be invoked when the gateway itself realizes the IP change has happened. For example: localhost/update?domains=mydomain.com;*.mydomain.com&ip=%i where %i is replaced with the actual new ip address from Unifi.

If there was an option to host a tiny web api with an endpoint that took these parameters it could force the update in a more timely fashion than relying on 5 min cron jobs. Even if there was no IP parameter passed and it could just trigger an update sooner that would be a helpful place to start.

Extra information?

I also looking for such a solution. Fritzbox offers an option to call a dyndns endpoint when the ip has changed.
Example documentation with the available parameters: https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-6660-Cable/30_Setting-up-dynamic-DNS-in-the-FRITZ-Box/

Im not a fan of randomly calling an endpoint in a fixed interval to check for ip address changes and I would like to have such an enpoint to only run the "update" when fritzbox calls the docker container api url.

I would also be very interested in this. I used to do DDNS updates via my own tool until I stumbled upon this great project, which - funny enough - picked exactly the same name as my (unpublished) tool. 🤓

Anyway, this feature is exactly the only thing that's missing. It's not terribly bad to wait a few minutes after a disconnect happend. Still, it would be even better if the DDNS update would happen instantly as soon as the internet connection comes back online.
A simple HTTP endpoint on another port would do the job, and everything is covered by Gos standard lib, so no new dependencies etc. required at all.

I would be interested in having an endpoint to force update because sometimes the IP update fails, like below:

Having and endpoint helps triggering an update manually.
