Comcast Plans IPv6 Trials In 2010
Mortimer.CA writes "In a weblog posting, Jason Livingood, Executive Director of Comcast's Internet Systems has stated that they're beginning public trials of IPv6; Comcast hopes 'that these trials will encourage other stakeholders to make plans to continue, or to begin, work on IPv6 in 2010 so that all stakeholders do their part in ensuring the future of the Internet is as bright and innovative as it has been in the past.' Interested guinea pigs can volunteer at Comcast6.net (FAQ). Those who have IPv6 connectivity via other means can check out their IPv6-only web presence."
I was part of the team that wrote the IPv6 portion of the DOCSIS 3.0 specs. Although DOCSIS 3.0 added a huge number of features, the two that the cable companies were most desperate for were channel bonding (so they could compete with fiber) and IPv6 support.
IPv6 has been internal testing with major cable operators for several years now. Comcast was always likely to be the first to deploy it (for reasons that I can't go into) but I expect the other major operators to follow suit within a year or two.
