Avahi now runs in Ubuntu to serve as a nameserver on 127.0.1.1. How do I figure out which nameserver(s) Avahi auto-discovered to use?
Seems that this is ultimately still coming from Network Manager.
I was able to find my eth0 device with:
# nmcli con show NAME UUID TYPE DEVICE Wired connection 1 eaa034b4-c9a6-3469-9c20-d0922e777d6b 802-3-ethernet eth0 cni0 6f4e3d15-6ba1-43a2-8c29-609676e5b7fc bridge cni0 docker0 5112d4fe-6490-4f9a-bce2-02651b2bd4a7 bridge docker0
and then find the nameservers that avahi ulimately uses with:
# nmcli con show "Wired connection 1" | grep domain_name_servers DHCP4.OPTION: domain_name_servers = 172.20.43.4 172.20.38.12 10.100.2.155
