IPv4 Depletion

IPv4 Address Options

Due to depletion of its IPv4 Free Pool, ARIN is no longer able to fulfill requests for IPv4 address space unless you are an organization requesting a small block of IPv4 address space to facilitate the transition to IPv6 (per NRPM 4.10) or micro-allocations for specific purposes such as the operation of exchange points (per NRPM 4.4 and 6.10 ).

Your options for getting IPv4 address space are:

Waiting List for Unmet Requests

Submit an IPv4 request and go on the Waiting List for Unmet Requests - Requests on the waiting list can only be filled when ARIN adds IPv4 address space to its available IPv4 inventory. This usually occurs when a registrant returns IPv4 address; upon revocation by ARIN (typically for non-payment of annual fees); after address space distribution to ARIN by Internet Assigned Numbers Authority (IANA); or when otherwise made available to be re-issued.

Transfers to Specified Recipients

Seek IPv4 address space via a Transfer to Specified Recipients (NRPM 8.3 or NRPM 8.4)

  • If you have identified an organization that is interested in transferring an IPv4 address block to you, you can enter directly into the Transfer Process via ARIN Online.
  • If you are looking for an organization with IPv4 addresses to transfer, you can get pre-approved for a transfer while you locate available resources. Pre-approvals are valid for 24-months.

Specified Transfer Listing Service

You can register for ARIN's Specified Transfer Listing Service to help find an organization that ARIN has validated as having IPv4 resources eligible for transfer.

Adoption of IPv6

To ensure the growth of your network well into the future, you might also consider requesting IPv6 address space directly from ARIN.

Note: Please refer to the IPv4 Countdown Plan page for a description and history of how this process has been managed.
