    Type of Resource Transfer Request Criteria for ARIN to Consider Transfer
    Transfers Based on Mergers, Acquisitions, and Reorganizations
    • ARIN will consider requests for the transfer of number resources in the case of mergers and acquisitions upon receipt of evidence that the new entity has acquired assets that used the transferred resources from the current registrant. Acceptable types of documentation include:
      • An authenticated copy of the instrument(s) affecting the transfer of assets, such as:
        • Asset purchase agreement and bill of sale
        • Finalized merger or amalgamation agreement filed with a province/state/federal government
        • Finalized court order
      • SEC or other public filings that document the transfer of assets
      • Authenticated documentation showing name change, such as
        • amended articles of incorporation
        • state/province/federal government verification of name change
    • If multiple transactions connect the old and new organizations, documentation will be required for each transaction. You are welcome to redact any financial or otherwise sensitive information. If necessary, ARIN has a standard nondisclosure agreement available.
    • In the event that number resources of the combined organizations are no longer justified under ARIN policy, ARIN will work with the resource holder(s) to return, aggregate, transfer, or reclaim resources as needed to restore compliance via the processes outlined in current ARIN policy.
    Transfers of Released Number Resources to Specified Recipients
    • ARIN has received verification that the authorized resource holder wishes to release the resources to an organization within the ARIN region, and that the intended recipient has a demonstrated need for the resources based on current ARIN policy
    • Requests for transfers under this policy must be submitted by an authorized individual from the registered organization.
    • The recipient organization may receive blocks of IPv4 addresses or ASNs under an 8.3 transfer as long as they can demonstrate the need for the resource under a current ARIN policy (ISP initial/additional, end-user, multi-homed ISP/end-user, etc).
    • The recipient organization may be required to complete a resource request form in order to provide the detailed information needed to verify that they qualify for the number resource under an existing ARIN policy.
