dyndnsupdater
A CLI (written in go) for primarily updating the external IP of the current machine in the A record for the specified domain name. It can be run in a loop to perform these updates periodically and export the metrics from this updater for prometheus to consume. The tool also prints other information (eg. Geolocation, internet provider, etc.) about the external IP which is also exposed through the prometheus metrics.
- CH TXT responses from
whoami.cloudflare.
is used as the primary source to determine the external IP. - ipinfo.io and ipify.org are also used as additional sources to validate the obtained external IP.
- ipinfo.io provides geolocation and internet provider information.
Supported DNS APIs for updating the DNS records
Only Cloudflare
is supported at the moment for DNS management. If other
providers need to be supported, please file an Issue or submit a pull request
with details for further discussion.
Usage
Just build and run the binary with the necessary flags depending on your use case.
TODO: Add more details about the flags, invocations, examples, etc.
