It nothing can resolve the hostname as ipv4 it will also try ipv6.
Ideally the mdns4_minimal should get replaced as well, but there's some
handwaving on the internet stating it will slow things down if your ipv6
network is misconfigured.
Since I can't verify that slowdown I've opted for the safe way and only
do ipv6 lookup in the fallback entry.
