On 23 April 2012 during ARIN XXIX in Vancouver, Leslie Nobile, Director of Registration Services gave a presentation on ARIN's plan to manage the distribution of its remaining IPv4 address pool.
The ARIN community has worked together over the last several years in developing policy to manage how ARIN allocates and assigns IPv4 addresses. ARIN has reviewed and refined its procedures to create an IPv4 Countdown Plan explaining how IPv4 requests will be processed as the remaining IPv4 address pool is distributed. We have posted the details of the plan at:
The page includes links to the presentation given by Ms. Nobile at the ARIN meeting, and we invite you to view the webcast archive as well in order to see the presentation and the discussion that ensued.
The IPv4 Countdown is a dynamic process and we will keep the community up to date on the status of the ARIN IPv4 address pool. ARIN will be updating and adding more information to the IPv4 Countdown page as we move through this process, so we strongly encourage you to pay attention to announcements and keep track of the current IPv4 inventory by monitoring the counter on the ARIN homepage. Because the IPv4 inventory may fluctuate on a daily basis, it is not intended as a tool to guide the timing of your IPv4 resource requests.
