I've now got one instance with this condition again. >From what I can see from the logs is that systemd-resolved started using some >other DNS server: First one in my network where I do not have control over (ipv4: 192.168.178.1 , somehow it turned up with this fairly correct address : my router) Then one which I do not know at all (ipv6: fd00::464e:6dff:fefb:1b50 , don't know where that is)
What I would like is to have it stick to 192.168.178.2 , which is used to supply addresses to virtual machines. I'll leave systemd-resolved running as is for now for inspection.

At some moment the service just stops working correctly and is not able to recover. I can reset the service by restarting it: systemctl restart systemd-resolved.service I've also tried to set the caching off, but it still fails on me occasionally (on 18.04 as well).
