IPv4 Waiting List
ARIN’s free pool depleted in September 2015. The IPv4 Waiting List is one of several ways an organization may request IPv4 addresses from ARIN. Other available options are to transfer resources or request IPv4 addresses from pools reserved specifically for micro-allocations (NRPM 4.4) or Dedicated IPv4 block to facilitate IPv6 Deployment (NRPM 4.10).
Waiting List Process
If an IPv4 Waiting List request meets current policy requirements, the organization will be placed on the IPv4 Waiting List for their approved block size. The qualifying organization must specify the smallest block size they would be willing to accept to fulfill their request. Receipt of IPv4 space in any amount via IPv4 Waiting List, 8.3 Specified Recipient Transfer, or 8.4 Inter-RIR Transfer removes the organization from the IPv4 Waiting List.
As IPv4 addresses become available, typically through revocations due to non-payment, they will be used to fill requests on a first-approved basis, subject to the size of each available address block.
Please note the following:
- Organizations which hold more than a /20 equivalent of IPv4 space in aggregate (exclusive of special use space received under section 4.4 or 4.10) are not eligible to apply.
- The maximum-size aggregate that an organization may qualify for at any one time is a /22.
- An organization may only have one request on the IPv4 Waiting List at a time.
- Once a request is added to the IPv4 Waiting List, the smallest acceptable block size may be adjusted by the requestor at any time, however the maximum block size cannot be changed. To request a larger block, the organization must close their existing IPv4 Waiting List ticket and submit a new request for the larger block. The new request will be added to the IPv4 Waiting List in the order in which it is approved.
- If an organization declines to accept a block that becomes available, ARIN will consider the request fulfilled and will remove the request from the IPv4 Waiting List.
- Organizations must be current on all fees at the time a block becomes available. Organizations with an existing ARIN billing account will be notified of any past due fees and may remain on the IPv4 Waiting List, but will not be eligible to receive IPv4 addresses.
- If an organization’s account is revoked for non-payment, their ticket will be removed from the IPv4 Waiting List. If the account is later reinstated and returned to good standing with ARIN, the organization must submit a new request, and the new request will be added to the IPv4 Waiting List in the order in which it is approved.
- Per ARIN policy, when an organization’s IPv4 Waiting List request has been filled, the organization must wait 90 days after receiving said distribution before applying for additional space. This restriction applies to all organizations unless a waiver is requested and granted in accordance with policy requirements.
- Per ARIN policy, any IPv4 address space distributed from the waiting list cannot be transferred to another organization for 60 months, with the exception of Section 8.2 transfers. After 60 months, the space can be transferred.
- When an organization is notified that an IPv4 block is available, ARIN’s Financial Services will request a Registration Services Agreement (RSA) and/or registration fees when applicable.
Additional information and instructions for submitting an IPv4 request for placement onto the IPv4 Waiting List can be found on the Request IPv4 Addresses page.
Waiting List Status Report
Recent and Upcoming Waiting List Distribution
The table below represents the current state of the Waiting List for Unmet Requests. This list is provided in chronological order beginning with the oldest waiting list request. The “Date and Time Added to Waiting List” column represents the date and time that the request was placed on the waiting list.
This table is not indicative of the order in which requests will be filled. That order depends entirely upon the order, size, and quantity of IPv4 address blocks that ARIN receives and places back into its IPv4 inventory.
