From the horse’s mouth
Comcast are rolling out a pilot deployment of IPv6-based Internet service. Here the customers will be those using a computer that is connected directly to a compatible DOCSIS 3.0 cable modem.
The computer will have to run Windows Vista or 7 for the Windows platform or MacOS X Lion for the Macintosh platform. This is because these operating systems are known to support a dual-stacked IPv4/IPv6 setup which the service will be based on. As well, these services will be provided with a unique full IPv6 address. Of course, Comcast will have 6to4 IP gateways in the network to bridge the IPv6 and IPv4 networks.
At the moment, there will be the rough edges through the deployment of this trial setup while the bugs are ironed out. A subsequent trial in the near future will then look at the use of home networks, but I would like to have this trial examine networks that are comprised of IPv4-only devices as well as dual-stack IPv4/IPv6 devices. This would also encompass access to legacy and IPv6 Internet services from both the legacy and the IPv6 devices.
Most likely this rollout will appeal and be targeted to some of the computer “geeks” who want to dabble in the latest setups. But I see it as a chance for Comcast, a mass-market cable-Internet provider, to put IPv6 through its paces before the full deployment commences. It also is an open chance for Comcast to put their findings about how their IPv6 deployment went to other cable-Internet providers who will be facing a requirement to roll up to this technology.
