IPv4 Depletion Status at ARIN
What happens after ARIN depletes its free pool of IPv4 address space? Will there be a Phase 5 added to the IPv4 Countdown Plan? Is the IPv4 inventory counter always accurate? These are just some of the questions we’ve been hearing in recent weeks. We understand that IPv4 depletion is causing confusion and uncertainty, so we’d like to try address some of these common questions and provide some additional information on the current status of IPv4 run-out at ARIN.
Current Status of Phase 4 of the IPv4 Countdown Plan
ARIN has implemented Phase 4 of our IPv4 Countdown Plan, and as a result, our response time for IPv4 requests has increased from our organizational goal of two business days. We acknowledge that this situation has caused some frustration in the community, and we are making adjustments to our IPv4 request procedures in an effort to improve response time. But the first question is what changed in Phase 4, and why? First - Phase 4 requires “team review” for all IPv4 requests. This allows us to ensure all organizations are being reviewed under the same set of requirements. By having at least two analysts review each new IPv4 request (and responses to an existing IPv4 requests), we have additional verification that each is handled in accordance with policy.
5 Misperceptions about ARIN IPv4 Depletion
There has been some animated discussion and speculation about ARIN’s IPv4 depletion, in various places ranging from forum discussions to Twitter haikus. In much of the discussion about this news, we did find a few persistent misconceptions. So we thought we would take the opportunity to clear up a few of these, and provide some facts to help you better understand the situation.
ARIN Reaches Final /8 of IPv4 Address Space
On 23 April 2014, ARIN’s IPv4 address inventory dropped to 1.00 /8 (the equivalent of 16,777,216 addresses) which triggered the final phase of our IPv4 Countdown Plan. Read the official ARIN announcement on this milestone. What is the answer to IPv4 depletion? IPv4 depletion should come as no surprise to anyone and clearly underscores the need for IPv6. The sheer size of the IPv6 address pool will more than meet the needs of the growing Internet now, and well into the future.
