Hi Rowland, all,

you can read about the ubuntu systemd-resolved here:

https://manpages.ubuntu.com/manpages/impish/man8/systemd-resolved.service.8.html

But I tend to deactivate it and turn to the classical setup with 
/etc/resolv.conf .

This can be done by setting

  DNSStubListener=no

in
  /etc/systemd/resolved.conf

and removing the symlink, replacing it with a traditional resolv.conf file.

You then also  should disable the stub resolver:

systemctl disable --now  systemd-resolved

Hope this helps, Jakob
