Comcast Activates First Users With IPv6 Native Dual Stack Over DOCSIS

[Brzozowski, John]

Mark,

The short answer is as follows:

* this is a trial, so we are taking a conservative approach
* this may not be the default configuration for production roll out
* lastly, the gateway does not need any more than a /64 and as such did
not provide a hint for anything shorter
