Thanks for the interesting facts, I didn't know that about Comcast. I still think that widespread ISP support will lead to rapid adoption, with 50% of traffic being switched over in a decade once that occurs. How old is your cable modem and router?
My cable modem and router are brand new since I deliberately bought IPv6 capable ones so I can use IPv6 when it becomes available.
Mobile seems to be the area with the most IPv6 adoption. Verizon Wireless has 25% of traffic on IPv6. Verizon required IPv6 for its LTE network, and many of the popular mobile sites like Google and Facebook support IPv6.
Mobile definitely seems to be leading the way. I know the pace of obsolescence may be slowing a bit, but I still suspect that most consumer cable modems and routers will be replaced within a decade, similar to the pace of 802.11n adoption. It is troubling that ipv4 only ones are still being sold. So many negative comments here, but I still believe ipv6 will be rapidly adopted in the coming years and that all this concern about carrier NAT and the depleted ipv4 address space will become irrelevant in short order.
