Your issue is site-specific; most likely your modem is outdated, but your router may also be configured to not try to acquire a block of IPv6 addresses.
Interesting. No communication from them. I figured this is the sorta thing they'd mass contact people about to update.
I remember asking the installer about 3 years ago about it. He said I'd have it as soon as they turn it on at the central office...
I'm not really too worried about it yet as it's not a problem really yet. I hate talking to support people.
I went to the IPv6 page and it's not showing a V6 IP Address http://screencast.com/t/Xuq4VOfnS but the Dynamic page for IPv4 displays it in those text boxes(editing is disabled on them even though they look like inputs. A bit confusing UX if just looking at the image)
So it appears my firmware has it... strange. This is on the modem itself, not the router as it's a all in one.
Just found this: http://forums.timewarnercable.com/t5/IPv6/Not-getting-IPv6-A... from two months ago "I got someone from Tier 3 on the phone and he told me it was not available yet in my area." so hmm, sounds like some areas might be last to get it then.
