forget about it if you want to run it on an IPv6-only VPS, it's not ready yet

There's not any common reason I can think of to go ipv6 on the backend. KISS --if there's enough IPs in a private v4 range, use them.

If you need/want to serve v6 clients, put a v6 load balancer in front. You're likely going to need that lb anyway.

I think the use case was running on a cheap server that actually doesn't have ipv4 connectivity

correct

> KISS

ipv6 and routable ips is way simpler than patching layer 2 networks together.

K3s absolutely supports ipv6-only
