Comcast Activates IPv6 Trial Users
Spacecase writes "Comcast announced the first group of trial users have been activated on their IPv6 Native Dual Stack solution. Considering the recent news about IPv4 addresses becoming scarce, this looks to be one of the better solutions to get out of the IPv4 problems."
Big heavy winter storms can do that, yes.
Comcast has a slightly unusual situation. They are so massive that their "control plane" network has exhausted 10.0.0.0/8. That means afaict they are now using public IPs not just for customers but for internal use as well. The space that most ISPs would use to put their customers on ISP level NAT is ALREADY TAKEN for their "control plane" network.

Given that they have little choice but to go IPv6 for thier internal networks (or "federate" the network but that is a large management headache) before IPV4 addresses run out it is not that surprising that they are proposing to offer it to customers as well.
