IP Freely writes "At this year's Internet Engineering Task Force meeting in Philadelphia, conference organizers shut off IPv4 for an hour. Surprisingly, chaos did not ensue. 'After everyone got his or her system up and running, many people started looking for IPv6-reachable web sites, reporting those over Jabber instant messaging — which posed its own challenges in the IPv6 department. I was surprised at the number of sites and wide range of content available over IPv6. Apart from — obviously — IPv6-related sites; they ranged from "the largest Gregorian music collection in Internet" to "hardcore torrents." Virtually none of the better known web destinations were reachable over IPv6. That changed when ipv6.google.com popped into existence.'"
I think there's a world market for about five computers.
