Public bug reported:

After upgrading to the latest package the systemd-resolved service fails
to resolve names for local network.Manually invoking nslookup works
fine.

The only suspicious output from journalctl seems:
systemd-resolved[858]: Server returned error NXDOMAIN, mitigating potential DNS 
violation DVE-2018-0001, retrying transaction with reduced feature level UDP.

The latest change in that package is:
 * SECURITY UPDATE: Unprivileged users are granted access to privileged
    systemd-resolved D-Bus methods
    - d/p/0001-shared-but-util-drop-trusted-annotation-from-bus_ope.patch:
      drop trusted annotation from bus_open_system_watch_bind()
    - CVE-2019-15718
