Comcast quietly rolls out IPv6 to subscribers

Zyrtec · Nov 12, 2011

Deployment of IPv6 is still in its infancy, but Comcast has started pushing the protocol out in a limited fashion to subscribers in select markets. That makes Comcast the first national ISP to deploy IPv6 and it is likely that others will follow suit in the near future.

IPv6 is the successor to IPv4, which aims to solve the long held apprehension that planet Earth will run out of available IP address space. Thanks to local network address translation (NAT) though, fears have been continually postponed. Because NAT allows homes and businesses to share a single Internet address amongst many devices, the number of unique IP addresses required for the world's population to access the web is far less than it would be otherwise. The newer protocol bumps up IPv4's limit of 4.2 billion unique address to 340 trillion trillion trillion, which ought to satiate the global hunger to be online for some time.

Interesting. The push is starting sooner than I had thought

Comcast claims their IPv6 rollout will first appear exclusively on computers connected directly to their cable modems or gateways. Routers will not receive IPv6 addresses themselves, although I do wonder if users change the MAC hardware address on their router, if they will receive an updated IPv6 number -- router permitting, of course.

When it becomes more wide-spread, I guesss peole with ipv6 - incompatible routers will have no choice but to upgrade.
