ARIN Confirms IP Address Distribution Practices; Policies Do Not Encourage Profit-driven Speculation

Chantilly, VA – The American Registry for Internet Numbers Board of Trustees released a statement today that assures ARIN will continue to facilitate the policy development process that defines how Internet Protocol (IP) addresses are distributed in its region, and also reaffirms that ARIN’s policies do not encourage profit-driven speculation in IP addresses.

IP addresses are unique numbers that computers use to move information over the Internet. IP version 4 (IPv4), the currently prevalent version, contains just over four billion unique IP addresses, which is not enough to support the growing number of Internet-enabled devices. IPv6 is a new numbering system that provides an address pool billions upon billions of times larger than IPv4. 

ARIN uses an established open and transparent policy process to facilitate the Internet community’s decisions regarding how ARIN distributes these finite community resources. According to today’s statement, "the current resource management mechanism is fully sufficient to address the upcoming shortage of IPv4 addresses, and a continuation of sober and responsible enforcement will ensure continued maximum benefit to and protection of the entire Internet community."

"This is important because it reaffirms ARIN’s dedication to its well-established principles of Internet governance, universal access, and the stabile functionality of the Internet."
