It’s official. The last of the IPv4 address space has been allocated to the RIRs. This means there are effectively no more IPv4 addresses available.

Since around 1995, we’ve had the option of IPv6, but it’s deployment has been quite slow. Why, one asks? It’s probably easier to ignore the problem than work on it too soon.

Comcast is one of the few ISPs using IPv6 in places customers can see. Cox, my ISP, doesn’t seem to even know what IPv6 is. I assume they’re going to continue to use NAT until hell freezes over. Which isn’t bad, I think hell has IPv6.
