Hi, I live in Germany and only have public IPv6. My address changes only very, very rarely and has never changed in the time I’ve been self-hosting.
I also have a very small, pretty cheap VPS with static IPv4/IPv6 – which would seem like a great fit for some sort of tunneling/proxy setup. Now comes the question: What/how should I use it? I would like to not have the additional latency for IPv6 enabled hosts, can I just setup a reverse proxy for IPv4? Would Tailscale work for my usecase, what are some resources you found useful when using it?
Currently, I’m just hosting everything IPv6-only and hoping my address never changes, but that does not work for everyone, as especially many new buildings with fiber optic connections still only have IPv4 (strangely).
Another option if you need public access without something like tailscale would be to use ddns and a AAAA record. Something like https://github.com/ddclient/ddclient would help do that.
That way if the IP changes, you’d pick up on the change for your vanity url within a few minutes… and can get https certs for that url as well.
Edit: I reread the OP. This doesn’t help if clients need direct ipv4. Sorry about that.
