 Nico | Just found this, if I have the time, I will definitely test this...

I even have a test prepared 😂 https://github.com/secshellnet/nixos-tests/pull/3 | 19:25:27 |
 Tom | ah, nice find that gist | 19:37:16 |
 Marcel | when I've thried the MR in networkmanager with nixos I had to diable the firewall. I have not yet investigated which changes would need to be done. | 19:39:16 |
 hexa | I don't suppose that networkmanager allows matching its version by the dhcp server | 19:41:27 |
| hexa | to understand whether the version supports 464xlat | 19:41:45 |
| hexa | I mean, I can certainly send out pref64/v6-only-preferred unconditionally | 19:43:14 |
| hexa | but last time I checked some clients behaved weirdly | 19:43:31 |
| Marcel | in dresden the only clients that behaved strangly was Sandro 🐧 kde connect because it forces v4 even if both clients have v6 addresses. All other problens were solved with pref64 and ipv4only.arpa. records. | 19:47:31 |
| Marcel | and coperate VPNs | 19:47:57 |

| Tom | Freifunk Karlsuhe seems to have rolled out IPv6 mostly at the end of last year https://chaos.social/@ffka (German) It would probably make sense to talk to them at some point.
But it makes me kinda hopeful that the Apple weirdness i observed in 2024 has disappeared enough (by patches and people constantly upgrading their devices) that it becomes viable at some point.
But i think my Pixel 8a with current Graphene OS still has the issue that the network stack sometimes becomes unresponsive and only a reboot fixes if it's in a ipv6 mostly enviroment. | 20:15:30 |
| Tom | yeah, it seems to be working for me with 1.57.2-dev | 21:41:14 |
| Tom | But looking at tcpdump it doesn't seem like you can even easily tell (if at all) it's a networkmanager dhcp request. So matching based on version seems even more out of the question.
(You could ofc set ipv4.dhcp-vendor-class-identifier but that doesn't seem scalable) | 21:59:19 |
