 hexa | mine says it offers stateful other config | 01:14:18 |
| hexa | router adverts are part of stateless autoconfig | 01:14:40 |
| hexa | and dhcpv6 also has a stateless mode | 01:14:54 |
| hexa | but stateful dhcpv6 means getting addresses on a lease | 01:15:04 |
 Charles | i get 3 sections like that | 01:16:07 |
| Charles | they all look the same, here's the last one:
Hop limit : 64 ( 0x40)
Stateful address conf. : Yes
Stateful other conf. : Yes
Mobile home agent : No

| Charles | thankfully there's no at-signs in this :^) | 01:17:30 |
| hexa | so for some reason they announce two different ULA prefixes | 01:18:16 |
| hexa | w/e | 01:18:21 |
| hexa | L2-3 means it would autostart DHCPv6 when it got this router advertiseement | 01:18:44 |
| hexa | * L2-3 means it would autostart DHCPv6 when it got this router advertisement | 01:18:46 |
| hexa | * L2-3 mean it would autostart DHCPv6 when it got this router advertisement | 01:18:52 |
| Charles | those being the fd00 ones? | 01:18:53 |
| hexa | yeah | 01:18:57 |
| hexa | fc00::/7 is unique local addresses | 01:19:04 |
| hexa | kinda like private address space for ipv4 | 01:19:18 |
| Charles | ah | 01:19:31 |
|  astravoid joined the room. | 01:19:44 |
| hexa | you really can achieve a lot with just networkd | 01:20:47 |
| Charles | seems that way | 01:21:06 |
|  relichunter joined the room. | 02:44:08 |
| Charles | hmm i'm getting
# ip route get $(dig AAAA google.com +short)
RTNETLINK answers: Network is unreachable
on the router machine again after rebooting it without any extra changes
| 03:00:47 |
| Charles | [root@green:~]# ip -6 route
2601:1c1:8400:a440::/64 dev br-lan proto kernel metric 256 expires 331268sec pref medium
unreachable 2601:1c1:8400:a440::/60 dev lo proto dhcp metric 1024 pref medium
fe80::/64 dev br-lan proto kernel metric 256 pref medium
fe80::/64 dev en-wan proto kernel metric 256 pref medium
this looks wrong, there's no non-ULA address for en-wan

| hexa | no default route | 03:09:10 |
| hexa | networkConfig.IPv6AcceptRA = true;
| 03:09:45 |
| hexa | on wan | 03:09:46 |
| Charles | i'll try that | 03:10:33 |
| Charles | yeah that was it, nice, thanks | 03:11:23 |
| Charles | so now that i've got ipv6 addresses for my machines, are the non-privacy-extensions ones stable for use in AAAA records for public DNS records? | 03:17:28 |
