ARIN Outreach on IPv4 Depletion

Posted: Mon, 20 April 2009

The Board of Trustees has directed ARIN staff to contact, by certified letter, the CEOs of organizations that currently hold IPv4 resources in its region. The purpose of this effort is to raise executive awareness of the depletion of IPv4 resources and to encourage the active adoption of IPv6.

This letter will also serve as notification that, in response to the approaching depletion of the IPv4 free address pool, the Board has directed ARIN staff to take additional steps to ensure the legitimacy of all IPv4 address space requests.

Beginning 18 May 2009, ARIN will require that all applications for IPv4 address space include an attestation of accuracy from an officer of the organization. For information on this requirement, please see:
