Floating IP challenge (sopuli.xyz)

Ok, I'll share the ultimate guerilla-selfhosting challenge I can't figure out yet: what if my internet connection is G5 prepaid sim card in the middle of the woods (it actually is)? Apparently, I do have IPv6 more or less stable (undocumented), but that's kind of limiting at times. Seems barely possible, but!

The https://homebrewserver.club/low-tech-website-howto.html#network states:

The fiber connection itself is not necessary, especially if you keep your data footprint small, but a fixed IP adress is very handy.

which kind of implies someone figured out a way to get around it. Would someone share the trick?

Assuming you are not in a CGNAT, which is common for mobile networks: DNS with low TTL such as FreeDNS, pointing to your IP. And ofc, if you have a router in between, port-forwarding.

Otherwise, a VPN such as Tailscale. But you would need to install it on all your devices.

Otherwise, for HTTP(S) web services, a reverse-proxy such as CloudFlare.

Whoa, FreeDNS is a killer, I wish I knew about it before! I have domains to donate probably (unless they expired lol). I sure need to try that.
