except for nor using it at all, of course.

So I want to make my homelab IPv6 ready, because I have too much free time, i guess. There are two decisions that I'm currently unsure about:

  1. ULA or not. Do you have local only addresses or do your clients communicate using the global IPv6 address? Does not using ULAs work without a static IP from the ISP?
  2. DHCPv6 or is SLAAC enough?

For each question both options seem to be possible and I'm interested in your experience

Cheers

In the home/lab, I use public addresses with mostly SLAAC, but the host server has a static IP. I get A public /56 prefix via DHCPv6-PD from my ISP. There is a bit of a pain point if the prefix changes but it hasn’t happened since I moved here.

My ”production” setup is a bit more controversial. Since Hetzner charges extra for extra IPv6 subnets I simply created small /80 subnets for the VMs. While this does mean that SLAAC doesn’t work I can simply generate and assign static IPv6 IPs, same way as I do with IPv4. All generated from an ansible playbook that creates the VMs.

I have some ULA ranges as well, but it’s a bit of a special case as I only use it as internal IP ranges in a Kubernetes cluster. This is completely separated from the external network, with the cluster doing NAT to the node IPs anyway (even for IPv6), and all internal traffic being on an overlay network.
