US exhausts IPv4 addresses

Ars Says, "Remember how, a decade ago, we told you that the Internet was running out of IPv4 addresses? Well, it took a while, but that day is here now: Asia, Europe, and Latin America have been parceling out scraps for a year or more, and now the ARIN wait list is here for the US, Canada, and numerous North Atlantic and Caribbean islands. Only organizations in Africa can still get IPv4 addresses as needed. The good news is that IPv6 seems to be picking up the slack."
