Quick Guide To Internet Number Resource Transfers

Submitting a Transfer Request

Note: All transfer requests require an ARIN Online account linked to either an Admin or Tech Point of Contact record (POC) with the authority to request resources for a valid Organization Identifier (Org ID).

Via ARIN Online

To request a Transfer to Specified Recipients within the ARIN Region (NRPM 8.3), a Transfer Due to Mergers and Acquisitions (NRPM 8.2), or an outbound Inter-RIR Transfer (NRPM 8.4):

  • Log into your ARIN Online account
  • Select Transfer Resources on the left
  • Follow the instructions on the form

ARIN will collect a $300 USD, non-refundable processing fee for each transfer request of Internet number resources. This fee will be invoiced to the source organization's billing Point of Contact (POC), is to be paid before request evaluation begins, and does not guarantee approval. 

Once the transfer is approved and ARIN receives a signed Registration Services Agreement (RSA), any other applicable fees, and completes any required Inter-RIR coordination, your resources will be transferred.

In cases where number resources are transferred due to a company merger or acquisition (NRPM 8.2), the organization receiving the resources will be required to sign a Registration Services Agreement (RSA) and will have the option of retaining the legacy status of the IPv4 resources if they were issued prior to 22 December 1997.

Record Maintenance with ARIN

All resource holders are responsible for proper record maintenance with ARIN, including:

  • Org ID and POC information upkeep
  • Responsible IP address reassignment
  • Reverse DNS lookup maintenance (IN-ADDRs)
  • Payment of all annual registration renewal and maintenance fees
Transfer Request Requirements
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.
  • ARIN will proceed with processing transfer requests even if the number resources of the combined organizations exceed what can be justified under current ARIN policy as defined in section 8.5. In that event, ARIN will work with the resource holder(s) to transfer the extra number resources to other organization(s) or accept a voluntary return of the extra number resources to ARIN.
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.
  • Address resources from a reserved pool (including those designated in Section 4.4 and 4.10) are not eligible for transfer.
  • 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 as defined in NRPM section 8.5.
  • 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.

    When completing the request, note that instructions for required fields are provided on the request form. To ensure prompt processing of your request, please follow these instructions exactly. Any errors found may result in the request being returned for correction.
Transfers of Number Resources to ARIN from another RIR
  • Source RIR confirms the authorized resource holder wishes to release the resources to the specified recipient within the ARIN region
  • Recipient organization demonstrates the need for the total amount of address space under a current ARIN policy as defined in NRPM section 8.5 by showing how the addresses will be used within 24 months.
Transfers of Number Resources from ARIN to another RIR
  • Authorized resource holder confirms release of the resources to an organization located within another RIR's service region
  • Source entities within the ARIN region must not have received a transfer, allocation, or assignment of IPv4 number resources from ARIN for the 12 months prior to the approval of a transfer request, unless either the source or recipient entity owns or controls the other, or both are under common ownership or control. This restriction does not include M&A transfers.
  • Address resources from a reserved pool (including those designated in Section 4.4 and 4.10) are not eligible for transfer.
  • Confirmation the specified recipient meets the requirements to receive the released resources under the destination RIR's inter-RIR transfer policy
