\"IPv4<\/a>The world is ending. the IPocalypse<\/a><\/strong> is upon us! As I (and a lot of other people) have been warning<\/a> for a while now, North America has finally run out of new IPv4 addresses<\/strong>. The American Registry for Internet Numbers (ARIN<\/a>), the group that distributes Internet addresses for North America,\u00a0said<\/a> Thursday it has assigned the last addresses in its IPv4 free pool.<\/p>\n

IPv4<\/a> dates back to 1981 and only has room for 4.3 billion unique addresses. IPv6<\/a>, introduced in 1999, should have enough addresses to serve Internet users for generations, according to ARIN.<\/p>\n

\"No<\/a>
\nAnyone who still needs IPv4 addresses can request them from ARIN, but they won’t have any to give away<\/strong> unless it gets more from the global Internet Assigned Numbers Authority (IANA) or returned addresses from users who don’t need them anymore.<\/p>\n

\"\"<\/a>According<\/a> to\u00a0PCWorld<\/a><\/em>, ARIN already runs a waiting list<\/strong> for requests, which they set up earlier this year. \u00a0Users can also buy IPv4 addresses on the IPv4 grey market<\/strong>\u00a0(rb-<\/strong>\u00a0I first reported<\/a> on the IPv4 grey market in 2011<\/em>) from others who don’t need them and are looking to make some money. Addresses recently were going for around US$10-$12 each, according to people who follow the transfer market.<\/p>\n

PC World<\/em> speculates that more North American addresses may go on the grey market now that ARIN has exhausted its pool of fresh ones<\/strong>. That event triggered a change in the organization’s rules for approving transfers: There is no longer any restriction on how often an address holder can request transfers to specified recipients.<\/p>\n

North American is just the latest to run out of IP addresses according to the Register<\/a><\/em>.<\/p>\n
