Also seeing this issue in Ubuntu 17.10 (artful) with:
dnsmasq-base 2.78-1 systemd 234-2ubuntu12.1
I can confirm that following https://askubuntu.com/a/968309/ resolves the issue!
Steps to fix the issue:
Added this line to /etc/default/dnsmasq:
DNSMASQ_EXCEPT=lo
Then restarting dnsmasq:
sudo systemctl daemon-reload sudo systemctl restart dnsmasq
No more systemd-resolved taking 99-100% of a CPU core!
