Waiting List for Unmet Requests

ARIN adopted a policy in 2010 in preparation for the day when it would be unable to fulfill qualified IPv4 requests.  This policy stipulates that ARIN establish a Waiting List for Unmet Requests.  The highlights of this policy text can be found below, however, ARIN encourages interested parties to review the full text, found in the Number Resource Policy Manual in Section 4.1.8.

If ARIN does not have an address block large enough to fulfill a qualifying IPv4 request, ARIN will notify the requesting organization of our largest available block size and ask whether the organization wants to accept that block size. At this point, organizations will have several options available:

Option 1

The organization accepts the largest available block, and ARIN approves the organization's request. 

Option 2

The organization chooses not to accept the largest available block (or if there are no blocks available of any size), the organization can choose to be placed on a waiting list of pre-qualified recipients.  Organizations being added to the waiting list will be able to specify the minimum block size they will accept.  Each organization may have only one request on the waiting list at a time.

  • When an address block becomes available, ARIN will fill the oldest request for a block of that size on the waiting list, subject to verification the organization still qualifies for the approved block size. 
  • When the block is issued, the organization will be removed from the waiting list and will be unable to receive additional IPv4 addresses for three months.
  • An organization may only receive one allocation, assignment, or transfer every 3 months, but ARIN, at its sole discretion, may waive this requirement if the requester can document a change in circumstances since their last request that could not have been reasonably foreseen at the time of the original request, and which now justifies additional space.

Option 3

An organization may choose to abandon its request and attempt to fulfill their need via the IPv4 Transfer Market.

Note: Organizations will be removed from the waiting list if they receive additional IPv4 addresses via transfer.
