Description: Can't ping google.com. It returns ping: google.com: Name or service not known. Expected is being able to resolve the hostname. (Note: currently the VMs can't ping outside so there's no automated check for the solution).
Test: ping google.com should return something like PING google.com (172.217.2.46) 56(84) bytes of data.
Time to Solve: 20 minutes.
