> I wish hosting providers would give you a local routed ipv4 on ipv6 servers with a default NAT server.
You mean like AWS NatGW https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gat...
Those are still per-customer and require you to dedicate an entire IP address to it. That's overkill for a server which mostly talks over ipv6 but needs to connect to an ipv4-only service like Github once in a blue moon.
Any services like this for Hetzner?
30 USD/month and 0.045 USD/GB for ingress it is ok if you are big. It is a cheap service to build yourself. I do feel the pain of it being hard to get IPv4 minimal connectivity on ipv6 only hosts, i.e. for me a 1 USD/GB would be fine.
