According to Comcast’s DOCSIS Devices page, http://mydeviceinfo.comcast.net/?s=i&so=1&e=0&d3=1&tier=-1&sc=84, the Cisco DPC3008 is not supported for IPv6.  You could always try enabling IPv6 on a system directly connected to the Cisco and see what happens. I’m not optimistic. 

I opted for my minimal-effort solution.  I installed a Motorola SB6121 and a 5th gen Airport Extreme and turned them on. Of course I configured the Airport Extreme with a name, management password, and confirmed IPv6 was set to to configure Automatically and Native.  When the Comcast drop was plugged in and Comcast authorized the modem, I had a multistacked LAN. 

Going on 11 months of IPv4/IPv6 service.  I’ve had about 1 hour of downtime.
