Comcast pushes IPv6 forward

But it’s going to be slow going, and for good reasons. Despite all IPv6 promises, there is still much, much testing to do before it’s ready for prime time.

Today Comcast revealed that it has started an IPv6 “pilot market deployment” as first step leading to nationwide rollout next year. Broadband providers like Comcast haven’t rushed the switch to IPv6 — despite an increasing shortage of IPv4 network addresses — because of lacking support, ranging from operating systems to network switches and other devices. Then there are security questions that only real-time use can answer.
