ARIN created an IPv4 waiting list in 2015 in an effort to continue providing IPv4 addresses to organizations in need. As part of the requirement, the organization has to provide a business use case for their needs and meet a certain level of criteria.
These IPv4 subnets become available typically through revocations due to non-payment or returned IPv4 space from organizations who are no longer using them. ARIN then fulfills requests on a first-come-first-serve basis, subject to the size of each available address block
The organization must qualify based on the following requirements:
The organization must own less than a /20 (4096 IPv4 addresses) in the ARIN region. If they have more than or equivalent to a /20 of IPv4 space in aggregate (exclusive of special use space received under section 4.4 or 4.10), then they are not eligible to receive IPv4 from the waiting list.
An organization may only request up to a /22 (1024 IPv4 addresses in aggregate) at one time.
An organization may only submit 1 x request for IPv4 space on the waiting list at any given time.
If you choose to purchase IPv4 addresses from a third party, your waiting list position will be considered fulfilled and will be removed.
After an organization is added to the IPv4 waiting list, they may only request to change the total IP’s requested to a smaller amount. If they want to increase the request to a larger IPv4 subnet, they must close this ticket and open a new one.
If the organization no longer has a need and declines the IPv4 block that becomes available, ARIN will consider the request completed and will remove them from the IPv4 Waiting List.
Organizations are required to be up to date on all fees at the time an IPv4 subnet becomes available.
If an organization’s account is revoked due to non-payment, the IPv4 waiting list position will be removed as well. The organization will need to submit a new request once they are up to date on late payments.
Once an organization receives the IPv4 addresses off of the waiting list, they are required to wait 90 days before applying for additional IPv4 space.
Any IPv4 address subnets obtained from the waiting list must wait 60 months (5 years) before being eligible to transfer to a third-party organization.
Once an organization is eligible to receive the IPv4 subnet from the waiting list, ARIN’s Financial Services will request a Registration Services Agreement (RSA) and/or registration fees when applicable.
Waiting list IPv4 allocations can take anywhere from 6 months to 12 months depending on the total available IPv4 subnets and total requests from organizations at any given time.
