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:
- 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?
- DHCPv6 or is SLAAC enough?
For each question both options seem to be possible and I’m interested in your experience
Cheers


My setup is a pile of kludges built on top of each other over the last two decades.
I started with ULAs distributed through DHCP, connected to named, which allows hosts do declare their own name and let me access local services as though I had a real domain.
My ISP eventually started supporting IPV6, but only assigned /128, so the ULAs got NAT-6ed out to the real world.
I eventually learned how to request prefix delegation from the ISP and set up SLAAC.
So now, my PIv6 clients have a) their link-local address, b) the ULA, c) a “privacy” SLAAC, and d) a unique SLAAC. All my internal services still refer to the ULAs.
I don’t think I’d recommend this system for someone setting up from scratch. The easiest thing would be to go with SLAAC, if you can get prefix delegation, and set your DNS/pihole to send the unique-SLAAC address of any servers you run.
This is hilarious to me.
“We’ve got 7.9 septillion addresses to play with in each of our v6/32 LIR allocations… if we follow the standard and give each customer a whole network prefix, that caps us at 4 billion customers per LIR! Nonsense, let’s just give every household a single v6 address.”
It’s like these people don’t understand what IPv6 is for.
