Your preferred connection:
You are on IPV4 : Remote name ec2-50-16-122-200.compute-1.amazonaws.com

This server is running dual-stack (it has the same name on both IPv4 and IPv6 networks). The information above identifies your preferred connection - typically IPv4 if you have a 6to4 tunnel, such as in Windows Vista.

The information above (if any) identifies your IPv6 connection. Vista/W7 users may have a 6to4 tunnel without realizing.

The information above (if any) identifies your IPv4 connection
Are you ready for IPv6 Day on June 8 ? (2011) Take this test: RIPE IPv6 Eye Chart
