Anyone self-hosters using IPv6 internally with k8s/k3s? (lemmy.ca)

Just wondering how many of us use ipv6 for our local hosts, as with my router upgrade, my ISP only allows me to have 253 IP ipv4 addresses (and I don't want to have to buy a new router/gateway, a 10gbe router/gateway is expensive).

Anyway, do you guys use statically assigned ULA addresses? Statically assigned global addresses? DHCPv6? SLAAC? What do you guys do for DNS resolution, avahi/mdns everywhere (given that ipv6 addresses seem to change all the time).

I've currently mostly gotten ipv6 working (dual stack) on machines I touch, my my k3s cluster is out of commission until I can figure out a way to not have them consume any precious ipv4 addresses.

I'm not even sure what prefix I want to choose for the cluster / service CIDR, should I be using a ULA or the one specified https://docs.k3s.io/installation/network-options#dual-stack-ipv4--ipv6-networking, 2001:cafe:42::

You really want to avoid NAT64 if possible. This thing is a nightmare to get working, and open source options to do it are not plentyful.

I remember that a few years back (2018 maybe ?), the FOSDEM team built an IPv6 only network for the attendees, and the NAT64 part was handled by proprietary devices because they couldn't get it to work with FOSS software.
