Best way to get IPv4 connectivity to my self-hosted services (infosec.pub)

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).

Small and stupid question.

Why don't use a ddns client to update your ipv6 evytime it changes? With a ttl of a minute your shouldn't be able to see any downtime...

I (genuinely) thinks you are trying to solve a small problem in the complicated and hard way.. M

Plenty of IPv4 only networks still exist from which you would not be able to access the services. I am in a similar situation as OP with my offsite address being IPv6 + CGNAT IPv4 and my own address being IPv4 only.

Plenty of ipv4 only in 2025?? Really?? Without a possibility to activate dual stack or just the dslite-crap?

I honestly didn't think this could be a real issue in those years.
