American Registry for Internet Numbers (ARIN) Runs Out of New IPv4 Addresses for North America

Stephen Lawson at PC World: North America has finally run out of new addresses based on IPv4, the numbering system that got the Internet where it is today but which is running out of space for the coming era of networking.

The American Registry for Internet Numbers, the nonprofit group that distributes Internet addresses for the region, said Thursday it has assigned the last addresses in its free pool. The announcement came after years of warnings from ARIN and others that IPv4 addresses were running out and that enterprises and carriers should adopt the next protocol, IPv6.

'ARIN IPv4 Free Pool Reaches Zero'

Anyone who still needs IPv4 addresses can request them from ARIN, but the organization won’t have any to give away unless it gets more from the global Internet Assigned Numbers Authority (IANA) or returned addresses from users who don’t need them anymore. ARIN already runs a waiting list for requests, which it set up earlier this year.

Users can also buy IPv4 addresses on the so-called transfer market 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.
