Just to chime in: Noticed slow machine and systemd-resolved taking 100% cpu. Edited /etc/systemd/resolved.conf to DNSSEC=no (not off, as "no" was commented out in the file). Tried systemctl restart systemd- resolved, but nothing changed. Tried killall systemd-resolved, nothing. Tried killall -9, and it respawned a well-behaved process. I recently installed dnsmasq when my computer failed to resolve anything. This is a fairly up-to-date Ubuntu 17.10.
