What does your IPv6 setup look like? (feddit.org)

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

I live in spain so the main ISP is well provided with IPv4 blocks and have zero incentive to deploy IPv6 outside of mobile networks. So the IPv6 deployment here is like 3% and I don't have access to it 🫠

Every discussion I have seen on the subject says that docker ipv6 is pretty busted from a security perspective and you have to implement a bunch of workarounds.

I don't have to time both to migrate to podman (and maybe have to run dual stacks for what isn't available) AND migrate to ipv6. But apparently the way podman does it is also kind of a hacky way (I am far from a networking expert) so I will sit with my pretty decent, secure, and working ipv4 lol

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.

I have that conf: /etc/sysctl.d/01-ipv6.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

But that falls under your exception. It seems to me that IPv6 causes more problems than it solves.

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.
