Figured: the additional IPs are listened on by LXC "devices"
configured on containers. I don't know if there's a command to query
for devices globally, anyway they can be queried for each container
with:

  lxc config device show <containername>

Also, `netstat -tnl` can be useful to see what's being listened on.
