 emily | but for servers I think local DNS64 can make sense | 13:13:42 |
| emily | since you can eliminate the v4 stack entirely | 13:13:53 |
 hexa | I would start by trying v6-only-preferred and pref64 | 13:13:55 |
| hexa | and figure out what breaks | 13:14:03 |
| emily | which is after all the goal | 13:14:03 |
| hexa | because sure enough a linux today will respect v6-only-preferred, not acquire an ipv4 address and not set up a translator | 13:14:28 |
| emily | pretty sure I don't have any clients that require actual dual stack thankfully | 13:14:31 |
| emily | (but I am sure that will tragically change at some point) | 13:14:42 |
| hexa | https://git.darmstadt.ccc.de/mrmcd/infra/nixos-config/-/commit/376c9759a87362077ad6534c4823821150e3d06d | 13:14:56 |
| emily | so I think I can skip v6-mostly for now | 13:15:01 |
| hexa | we did that for an event and it broke SIP 😄 | 13:15:05 |
| emily | I think networkd fixed that bug thankfully fwiw | 13:15:18 |
| hexa | yeah, but networkmanager? | 13:15:27 |
| hexa | dhcpcd? | 13:15:29 |
| hexa | not too sure | 13:15:34 |
| emily | actually I'm getting deja vu so maybe we talked about this before :) | 13:15:35 |
| emily | does NM do it too? silly | 13:15:43 |
| hexa | probably some version did 🙂 | 13:15:54 |
| emily | it's a total misreading of the RFC to respect that flag without setting up CLAT | 13:15:55 |
| hexa | and you know your LTS linuxes out there | 13:15:59 |
| hexa | this is absolutely about proper client discipline of course | 13:16:21 |
| hexa |

| hexa | openwrt exposes that as a knob 🥳 | 13:17:04 |
| emily | I didn't know WiFi even did multicast | 13:17:16 |
| hexa | uhh, at like base rate | 13:17:40 |
| hexa | so yeah, but slow | 13:18:03 |
| hexa | the fast rates are unicast only | 13:18:11 |
