Registration Services Department Report as presented by Leslie Nobile at ARIN's Public Policy and Members Meeting in April 2014. All ARIN 33 presentations are posted online at: https://www.arin.net/ARIN33_materials
2. Trends and Observations
• 18% increase in IPv4 requests in past 12
months over 12 months prior
• IPv4 requests becoming increasingly
complex
– Increase in number of back and forth
exchanges per ticket
– More potentially fraudulent requests
– More fraud reports from community
• More due diligence and staff time required for
these requests
2
3. Trends and Observations
• More out of region requests
– Difficult to verify justification
• Language barriers, no equivalent
way to validate data, frequent
requests, rapid growth
• More requests involving new technology
and services
– Some using very large amounts of v4
addresses
3
4. Trends and Observations
• Transfer requests increased 5%
overall in past 12 months over the
12 months prior
• Substantial increase in 8.3 and 8.4
requests in Q1 2014
• Expect continued increase in both
transfer and IPv4 requests as we
near depletion.

5. Service Level Impact
• ARIN Online ticket response times
– Increased from 1.08 days in 2012 to 1.65 days
in 2013
• Time required to complete IPv4 requests
– ISP: Increased by 7 days from Q1 to Q4 in
2013
– End user: Increased by 11 days from Q1 to
Q4 2013*
• Currently reviewing internal procedures
to find ways to streamline processes and
procedures
*includes billing and contract phase 5
6. Current IPv4 Inventory
• Available Inventory
– 1.26 /8 equivalents
• Reserved Inventory
– 8.88 /16 equivalents in the “RRH” bucket
(number fluctuates)
• (RRH = returned, revoked, held)
– /10 reserved for NRPM 4.10 “Dedicated
IPv4 block to facilitate IPv6 Deployment”
– 231 /24s reserved for micro allocations
*As of April 10, 2014 6
8. ARIN’s IPv4 Countdown Plan
Phase 4
• Begins at 1 /8 Equivalent left
• All IPv4 requests team reviewed
• Requests and responses processed in order
received
• Hold period for recovered resources drops
to 60 days
• Org has 60 days from approval to
complete payment and RSA
– Resources will be released back to free pool

9. IPv4 Churn
• IPv4 addresses go back into ARIN’s
free pool 3 ways
– Return = voluntary
– Revoke = for cause (usually nonpayment)
– Reclaimed = fraud or business dissolution
• 3.68 /8s received back since 2004
– /8 equivalent returned to IANA in 2012

12. IPv4 Waiting List
• Starts when ARIN can’t fill a justified
request
• Option to specify smallest
acceptable size
• If no block available between
approved and smallest
acceptable size, option to go on
the waiting list
12
13. Filling Waiting List Requests
• Oldest request filled first
–If ARIN gets a /16 back and the
oldest request is for a /24, we
issue a /24 to that org
• May receive only one allocation
every three months
13
14. Specified Transfer Listing Service
(STLS)
• 3 ways to participate
– Listers: have available IPv4 addresses
– Needers: looking for more IPv4 addresses
– Facilitators: available to help listers and
needers find each other
• Major Uses
– Matchmaking
– Obtain pre-approval for a transaction
arranged outside STLS
• Pre-approval is based on 24 month
demonstrated need 14
16. Inter-RIR Transfers
• 24 transfers completed (2,677 /24s)
• ARIN & APNIC for now
• Expectation is primarily ARIN to
APNIC given the early exhaustion of
IPv4 in the APNIC region

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. There are a number of variables that could accelerate or slow the rate at which ARIN moves through each phase. Some IPv4 space may be returned to IANA in accordance with global policy and new policies and/or larger requests could change intended plans and lead to faster depletion of the remaining IPv4 address pool.**Working with CMSD on communications planning for next phase
Returned number really went up with the return of the interop spacePeople are still returning
Low of 1.4 in 2003 to a High of 3.3 in 2008Pout Q1 util to a full year would be 1.23 /8 equivalents, which would be in line with 2011-2013. If you cite that, might be worth noting that “of course, it’s always possible we’ll get large requests that will increase that”.
waiting list software has been deployed so we’re ready for it whenever the first waiting list request comes in.
4,646 total membersee schedule change allows almost all ISPs to get IPv6 without incurring additional fees, which removed a possible disincentive for IPv6 adoption, but so far it hasn’t really changed anything. Thus far in 2013 maybe a 1% change in the number of ISPs that have IPv6.
