      Description

      In AWS, if you launch an instance and do name resolution for the public and
      private DNS names, you get the following:

      root@ip-10-8-22-128 ~]# dig +short ip-10-8-22-128.ec2.internal

      10.8.22.128

      root@ip-10-8-22-128 ~]# dig +short ec2-75-101-172-186.compute-1.amazonaws.com

      10.8.22.128

      Typically, this is done via split-brain DNS. For more information, please
