On the Horizon: Unmet Requests Policy Activation

 • Richard Jimmerson

We expect to take registration actions this week that will activate ARIN’s policy for unmet requests. For the first time, it is expected an organization will receive a block size smaller than they qualified for, and/or an organization will be placed on the waiting list for unmet requests.

Breaking down ARIN’s remaining IPv4 Pool

Breaking down ARIN’s remaining IPv4 Pool

 • Richard Jimmerson

At the time of this post, there is only .15 of a /8 remaining in the ARIN IPv4 free pool. The largest prefix that remains available is a /11. Within days, that /11 will either be issued to a qualifying organization, or broken down to make smaller prefixes available for organizations who have qualified for a block size that falls between a /11 and the next available block size in inventory.

IPv4 Request Pipeline

IPv4 Request Pipeline

 • Richard Jimmerson

Today we have .20 of a /8 remaining in the ARIN IPv4 free pool. At the same time, we have over 200 open tickets from organizations requesting IPv4 address space from that free pool. These requests are for sizes ranging from a /23 to larger than a /16. This does not count the many open tickets we have for /24s.

Defining Depletion: IPv4 Address Availability in the ARIN Region

Defining Depletion: IPv4 Address Availability in the ARIN Region

 • Richard Jimmerson

Here at ARIN we have been actively discussing the depletion of the IPv4 free pool for many years. Our goal has been to prepare the Internet community for the day when we can no longer issue IPv4 address space to those who need it. As that day approaches, there has been increased interest in how IPv4 addresses are issued and what the options are after we reach depletion.

IPv4 Depletion Status at ARIN

IPv4 Depletion Status at ARIN

 • Leslie Nobile

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

Current Status of Phase 4 of the IPv4 Countdown Plan

 • Leslie Nobile

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.

ARIN Reaches Final /8 of IPv4 Address Space

ARIN Reaches Final /8 of IPv4 Address Space

 • Leslie Nobile

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.
