The Consumer Electronics Association and cable operators have a long history of being at odds with each other, including CableCards and tru2way, but the two sides have figured out that in order to better serve consumers, there needs to be at least some level of collaboration.

The CEA announced yesterday that it had formed the IPv6 Transition Working Group, which features Comcast's John Brzozowski as its chair. As chief architect of IPv6 and a distinguished engineer, Brzozowski is Comcast's go-to guy on all things IPv6.

As the nation's largest cable operator and ISP, Comcast has been at the forefront of IPv6 testing and trials, so it's no surprise that the CEA has decided it's prudent to tap into Comcast's resources and expertise.

The working group will serve as a forum for retailers, broadband service providers and CE manufacturers to share information and work together on the IPv6 transition for consumer electronics.

"If your company makes Internet products, provides Internet service to consumers or relies on the Internet for services like streaming content, you may be impacted by the IPv6 transition, and you should get involved in this working group," said Brzozowski. "As part of a wider community of companies working on a successful transition to IPv6, Comcast is excited to lead this CEA effort involving manufacturers, retailers and content providers."

Service providers, consumer electronics companies and various organizations, including CableLabs and the SCTE, have been fervently working on the transition to IPv6 addresses.

The last block of IPv4 addresses was doled out earlier this year, but the remaining addresses could last until 2012 in the United States.

While IPv4 is reaching the end, IPv6 consists of 128 bits, compared with 32 bits in IPv4, resulting in approximately 340 undecillion IPv6 addresses versus the 4.2 billion available through IPv4.

World IPv6 Day was judged a hit by most measures when it took place earlier this year, but there's still plenty of work to be done in order to prepare for the transition to IPv6.
