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

Don’t use ULA, those are non internet routable addresses so they will never use v6 for internet things. Use the range assigned from your ISP.
SLAAC. Because Android has one ass of a dev who refuses to include DHCPv6I don’t use IPv6 on my lab. They been screaming to the bleachers since like 2010 that IPv6 is right around the corner due to lack of addresses, and I’ve still seen no real reason to want to adopt for it.
My current provider doesn’t even support it… so why should I?
In fact when I was in college taking classes on IPv6 we were told it would be everywhere next year.
This was 1994. Lol
Personally I don’t like it because it’s too overengineered for me. They should have added 2 bytes to IPv4 and called it a day. That means we would have had the address space of 65536 internets. Really plenty. IPv6 has too much space.
I have been ipv6 only for a few years due to my ISP and it made a few ipv4-only people very angry when they couldn’t access my websites

In what kind of godforsaken backwater do ISPs that don’t support IPv6 still exist!?
The largest of the 3 carriers in Canada.
Bell.
Does not support ipv6.
I didn’t know that Canada was basically Mordor…
Switzerland, we have the best and worst of both worlds. 25GBit Fiber home connections for less than 100 USD per month and ISPs that only support IPv4.
Which fiber provider doesn’t support IPv6? I thought it was only Swisscom mobile and its subsidiary’s which don’t support it (though from what I heard, even that is in testing now)
Small former Gemeinschaftsanntenne in my town and surrounding villages, I don’t wanna dox myself so can’t tell you the name. They probably have anywhere between 10-20k customers only. But afaik they are just one of many IPv4 only ISPs in Switzerland.

Ah, I see, that really does sound like a few places I know in Graubünden that wouldn’t be all too unfair to call “godforsaken backwater” (when it comes to the internet), despite all their charm. 😉
Yea that was similar to my response when I figured I would look into it a few years back. No ipv6 and no ip address rotation unless its offline for more than 24h, which makes thing simple
There are a few ISPs in North America that support ipv6, but many many don’t. As much as I detest the recent push toward “5G Internet to the Home”, it at least does increase adoption of IPv6 since (from what I understand) basically all mobile carriers are v6-only and do NAT64 for v4 support.
I don’t know if that translates to the 5G-at-home offering but it wouldn’t surprise me since most customers don’t care what address scheme is being used as long as Netflix works.
I use IPv6 local only. Everything else is IPv4. Reason being, my commercial VPN does not support IPv6 and I have reservations about leakage. My ISP already ships with IPv4 & IPv6.
I have that conf:
/etc/sysctl.d/01-ipv6.confnet.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1But that falls under your exception. It seems to me that IPv6 causes more problems than it solves.
My ISP provides a /48 for IPv6 via prefix delegation so all internal machines that support it have a ULA and DHCPv6. I have disabled SLAAC . In docker I assign a /64 of that prefix to docker containers. The local addresses is what most of the internal network stuff is based on (DNS etc) rather than the globally accessible address. The PD addresses are only about going onto the internet.
SLAAC actually is just fine, I just didn’t really want to be exposing the manufacturer information of the addresses online so preferred DHCP, but either or both together works from OpenWRT prefix delegation.
Idk. what assignment we use, but our ISP gave us (company) a prefix and we offer our services (for our team) IPv6 first. IPv4 is only used within the company network where a DNS server resolves the domains if needed.
It works great for us. If my private ISP would allow it, I would do the same.
So for you selfhosted services you use ipv4 only?
On work IPv6 external + IPv4 internal. Private ISP offers only the shitty dual stack light. I moved some services to a VPS.
IPv6 is disabled at the firewall. I’m just not in a hurry to redo my network.
Personal opinion, IPv6 has been on the table so long it’s no longer something I think about. 20 years ago I thought it was going to be amazing.

Disabled. IPv6 is slow af whenever I have it on. As soon as I disable it, my bandwidth goes full speed.
I’m not sure what they were thinking with that technology but it’s dead in the water and we need to find a better protocol. It’s also terribly difficult to memorize. The numbering scheme is worse than the Xbox naming scheme.
