What's the feature?

Publish port 8000 and port forward it with your router. The program would do a request to itself through the domain name to check it is accessible. If it's not it would get the public IP and update the record. That would allow for sub-second detection of an IP change.

It would however require the user to setup port forwarding and I would need to add authentication to the http server.

Extra information?

#136 might be a better solution if it's not rate limited as it removed the need to expose the http server on your router.
