The above image is my results on Comcast's IPv6 test site.
Edit: This is using an Arris TM722G modem, a Netgear WNDR3700 router, and Chrome 19.0.1084.52 on a Windows 7 laptop.
There is also: »ipv6test.google.com/
Let me know what message Google's IPv6 test website says to you guys. I am getting "You dont have IPv6, but you shouldnt have problems on websites that add IPv6 support.".
