I hope no one is using lack of configured DNS as a security measure! But I
can see a case for wanting lack of configuration to be a failure rather than
working but non-obviously not in the way you expected.
Use FallbackDNS= to override the built-in defaults, and set it to the
empty string if you want lookups to fail.
