What's the feature?

Once #136 is done, we should fetch public IP address over DNS over TLS+HTTPs, such that less is leaked, although the information is not really private or critical really. This depends on https://github.com/qdm12/dns/pull/58.

Extra information?

It's not sure Cloudflare or Google supports DNS over TLS/HTTPs for these utility ip echo endpoints

Although this may be "neat to have", since domain IP addresses are published as public DNS records, and since there are many services that map IP addresses back to domains (e.g. ipinfo.io) I'm not sure this is worth a lot of effort on your part.

Totally agree. Plus I doubt this would be supported by Google and Cloudflare, especially on these obscure echo endpoints! Closing

Re-opening as I have some use for such public IP fetching over TLS in other repositories.

I'll just add to the library but not use it in this program as it is indeed pointless here.
