I am confused by Stephane's orginal opening statement that | Prior to the switch to nplan, systems (in my case containers) would | DHCP for IPv4 and let the kernel do IPv6 auto-configuration whenever a | router advertisement comes in.
I opened bug 1732002 with information to the contrary. On my system, 16.04 images do *not* get ipv6 addresses, but current artful and bionic images do. I'm raising this because it seems that it was used for justification of a change to a stable release. $ lxc network show lxdbr0 config: ipv4.address: 10.75.205.1/24 ipv4.nat: "true" ipv6.address: fd42:eee5:7c43:3d62::1/64 ipv6.dhcp.stateful: "true" $ lxc list "(artful|xenial)-demo" +-------------+---------+----------------------+------------------------------------------------+------------+-----------+ | NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | +-------------+---------+----------------------+------------------------------------------------+------------+-----------+ | artful-demo | RUNNING | 10.75.205.208 (eth0) | fd42:eee5:7c43:3d62:3a42:611c:3f6f:1184 (eth0) | PERSISTENT | 0 | +-------------+---------+----------------------+------------------------------------------------+------------+-----------+ | xenial-demo | RUNNING | 10.75.205.143 (eth0) | | PERSISTENT | 0 | +-------------+---------+----------------------+------------------------------------------------+------------+-----------+ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717404 Title: IPv6 support regresses with nplan transition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nplan/+bug/1717404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
