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?
You run a dynamic DNS script. It reaches out to the DNS server (provided by whoever registers your domain name) every five minutes and says “my IP is x.x.x.x”.
The problem is that it takes a few minutes to update when it changes. That might not fit your use case.
