Using 237-3ubuntu10.1, with 8.8.8.8 as DNS server, the resolutions of nonexistant.ubuntu.com and secure.ubuntu.com both are retried with following messages in the journal:
systemd-resolved[1434]: Server returned error NXDOMAIN, mitigating potential DNS violation DVE-2018-0001, retrying transaction with reduced feature level UDP.

With 237-3ubuntu10, a similar message only appeared for "secure.ubuntu.com" NXDOMAIN query, but not for the nonexistant.ubuntu.com.
