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

    I use both ULA and global addresses. Servers set a token to make the last 64bits predictable, which simplifies dyndns. For some critical internal communication, I hard code the ULA address in my hosts file, for everything else, I rely on DNS (with global addresses). No DHCPv6.

    I usually just disable IPv4 on my VMs, unless there is a specific need for IPv4. Most container networks are single stack as well. I have a squid proxy that services can use to access IPv4 http/https destinations if really necessary (combined with some additional filter rules); ideally I would like to have 464xlat/a nat64 gateway, but I never bothered to set that up yet. I will likely do that when I buy a new router (end of year?). I expect all my devices to support CLAT by then, so that will be the end of IPv4 on my network.
