Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP
Apparently, your router is NOT unique.
I had originally used Auto-Detect for my WNDR3700v4 (factory firmware explicitly supports IPv6), and I wound up with the tunnel; however, by changing to explicit DHCP, I have the *correct* IPv6 range (2601:: block subseries, NOT the 2002:: block subseries used by the Comcast alternative 6to4 tunnel). This won't be unique to Windows 8 (or even to Windows), but it's a solid indicator as to whether the IPv6 detection of your router is working correctly or is wonky.
