IPv4 is depleted. Now what?
It has been more than three months since ARIN’s free pool of IPv4 address space depleted, and we have seen a few interesting trends in the registration operation since then. The waiting list for unmet requests has grown to over 200 organizations and the relative rate of incoming IPv4 free pool requests has decreased.
So Many Tweets, So Little IPv4
Since we announced that ARIN has zero IPv4 addresses remaining in inventory, we've heard a lot of social chatter around this historic event for the Internet. In fact, there have been thousands of tweets over the past few days - everything from the humorous to the serious. We couldn't possibly share them all, but here are a few that made us crack a smile
ARIN Reaches IPv4 Depletion
ARIN’s IPv4 free pool has depleted. This is an important milestone for the Internet as now we now usher in the age of IPv6. As previously described in this blog series, ARIN has been placing /24s on hold for organizations over the past few months. This occurred when an organization qualified for a larger block size, but was given the option to accept our only available block size (/24) available at the time.
IPv4 Depletion Update
Earlier this week ARIN and the other RIRs received a distribution of IPv4 address space from the IANA in accordance with their Global Policy for Post Exhaustion IPv4 Allocation Mechanisms. ARIN was issued a total of a /14 worth of IPv4 address space composed of one /15 block and two /16 blocks.
Tag This: IPv4 Runout
With less than 45K IPv4 addresses remaining in the ARIN inventory, IPv4 depletion here at ARIN is only weeks away. We thought it’d be fun to get your ideas about the tag line we should use when ARIN hits IPv4 runout. Maybe we’ll even take you up on a few of these. Here’s what you came up with so far
Waiting List for Unmet IPv4 Requests
As described in an announcement on 1 July 2015, ARIN has activated the Unmet Requests Policy. Organizations are currently electing to accept block sizes smaller than those for which they qualified or are electing to be placed on the Waiting List for Unmet Requests. So far, 21 organizations have elected to be placed on the waiting list and ARIN expects there to be over 100 soon.
On the Horizon: Unmet Requests Policy Activation
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
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
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
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.
