"IPv6 home networking support is generally improving," Brzozowski says, pointing out that three months ago only one home gateway model sufficiently supported IPv6 and now there are six involved in Comcast's home networking service. "The upgrade of home networking equipment is still required. Some customers may require the purchase of new hardware or a software upgrade."
Added Lee Howard, director of network technology at Time Warner Cable: "Less than 1% of home gateways have IPv6. I can't rely on home gateways, instead I have to rely on the 15% of people that have no home gateway and plug directly into cable modems for my initial IPv6 deployment."
Meanwhile, Comcast has enabled tens of thousands of customers across the country to use its original residential IPv6 service, which was for customers with standalone computers connected directly to cable modems. The standalone computer users that qualify for this service must run an operating system - such as Microsoft Windows 7, Windows 8 or Apple OS X Lion - that enables IPv6 by default.
Comcast's nationwide launch of stand-alone computer support for IPv6 began last November, and all of these customers are receiving dual-stack support for both IPv6 and IPv4.
Comcast is working towards the goal of having 1% of its 18 million residential subscribers use IPv6 by June 6, 2012, as part of its commitment to World IPv6 Launch Day. On World IPv6 Launch Day, more than 1,000 leading Web sites including Facebook, Google and Bing as well as ISPs such as Comcast, Time Warner and AT&T have committed to turn IPv6 on and leave it on for good.
"We're not there yet, but we are tracking to reach 1% by June 6," Brzozowski said.
Brzozowski says once Comcast has completed its IPv6 roll-out, the company plans to offer innovative new services on its next-gen platform. "We're already looking at ways to do more advanced intelligent home networking and communications and simplification of in-home services," he said.
