This test revolves google.com which retrieves (or may retrieve) IPv4 and IPv6 addresses
The test system is configured for IPv6 only i.e. IPv4 stack and configurations disable (except for OL9 systems which still have IPv4 stack but pure IPv6 configuration)

processing of IPv4 addresses should not be dependent on IPv4 stack enablement.
