Add assertion message if testDns ipv6 lookup reutrns ipv4.

Some partner test networks connect by VPN and if the connection
fails during the testing this test will fail as the local internet
provider intercepts the DNS request and returns an ipv4 address.

Added a message to check the network configuration and rerun the test.
