Current Fee Schedule FAQ

Changes to the Fee Schedule

What changes took effect with the most recent version of the Fee Schedule?

  • Increased the annual registry maintenance fee paid by end users for each IPv4 address block, IPv6 address block, and Autonomous System Number (ASN) from $100 to $150 USD per object. Registration Services Plan customers do not pay these annual registry maintenance fees as all services are already covered in their plan.
  • Legacy resource holders pay the same annual fee as End User organizations ($150 USD for each IPv4 address block and $150 USD for each ASN assigned to the organizations.) As of 1 July 2018, the total maintenance fees applicable to legacy resource holder organizations are limited to $125 USD annually, regardless of the number of legacy resources held under their LRSA.
  • Increased the initial and annual registration fee for ARIN Transfer Facilitators from $100 to $1,000 USD, in order to cover rising costs associated with services.

When was the current Fee Schedule implemented?

The ARIN Board of Trustees adopted the current fee schedule on 24 May 2018, and it was implemented on 1 July 2018. The new fee schedule reflects proposed modifications and community feedback collected from both the ARIN 41 Public Policy and Members meeting, as well as the Community Consultation that concluded on 25 May 2018. New fees are reflected in invoices due on and after 1 July 2018. The implementation of this new Fee Schedule was announced to the community 06 June 2018.

Why was the Fee Schedule changed in 2018?

The Fee Schedule was amended, following a community consultation, in order to recover costs in a fair and equitable manner via appropriate fees to maintain adequate funds for the long-term stability of the organization. ARIN has increased operating costs in recent years to meet customer demand for improved and broader services, and upon review, the Board of Trustees has called for both strategic cost management by the organization and some fee increases in order to preserve long-term organizational reserves.

What changes were made on 1 January 2017 in relation to transfer fees?

ARIN will collect a $300 USD, non-refundable processing fee for each transfer request of Internet number resources, including:

  • 8.2 Mergers, Acquisitions, and Reorganizations transfers; billed to the source (or legal successor) organization.
  • 8.3 Transfers to Specified Recipients within the ARIN region, billed to the source-side organization. The transfer processing fee is waived when the subject resources are under an existing Registration Services Plan (RSP), and no specific transfer processing fee will be charged to the recipient-side organization.
  • 8.4 Inter-RIR Transfers to Specified Recipients, a fee is billed to the source-side organization if within the ARIN region. This transfer processing fee is waived when the subject resources are under an existing Registration Services Plan (RSP). No specific transfer processing fee will be charged to recipient-side organizations.

This fee will be invoiced to the source organization’s billing Point of Contact (POC) and are to be paid before request evaluation begins. This fee does not guarantee approval of a transfer request.

Determining your fees

How do I determine my fees if my organization has multiple resources under one Org ID?

ARIN Online features a fee calculator for ARIN resource holders wishing to view an estimate of annual fees.

How are my fees determined?

ARIN determines fees per Org ID. End user fees are determined by service category corresponding to the number of resources held—IPv4, IPv6, and Autonomous System Number(s). ISP fees are determined by the service category corresponding to the cumulative size of IPv4 or IPv6. If an organization holds both IPv4 and IPv6 resources, the fee is based on the larger dollar value.

What do you mean by “cumulative total”?

The current fee schedule is based on the service category corresponding to the total amount of ARIN allocated IP address space to an organization, covered under an ARIN Registration Services Agreement (RSA). For example,if an organization has both a /32 of IPv6 address space (X-small service category) and a /17 of IPv4 address space (medium service category), that organization will be a medium service category as this is the larger of the two, and invoiced accordingly. For another example, if you have a /20 and a /21 issued by ARIN under RSA, and a /18 of legacy address space that is not covered under any agreement, your annual fees are calculated solely on your ARIN issued space and falls under the small Service Category of the fee schedule.

What if my organization is interested in becoming an ARIN Member?

ARIN automatically accords membership to organizations that receive direct IPv4 or IPv6 resource allocations (ISP). These memberships are annually renewed with the payment of an organization’s annual fee.

Organizations with Internet number resources from ARIN, such as direct assignments and/or ASNs, under either a signed Registration Services Agreement (RSA) or Legacy Registration Services Agreement (LRSA) may become an ARIN member by subscribing to the Registration Services Plan or by paying a separate annual membership fee of $500 USD.


Where do I find more information on the billing process?

Information about how billing works and the resource revocation, returns, and reinstatement process is available on the ARIN website.

How do I determine the term dates of my annual invoice?

The term of coverage is one year, renewing annually on the last day of each organization’s anniversary month. For example, for an invoice due 30 June 2016, the period of coverage would be 30 June 2016 - 29 June 2017.

Can I pay the renewal fees for multiple years?

No, the annual fee may fluctuate from year to year. Each year the renewal invoice is calculated by ARIN-issued IPv4, IPv6 address and ASNs to an organization by the number of objects or cumulative size.

Is each resource held under a single Org ID billed under a separate invoice?

No, ARIN generates a single invoice per Org ID. If an organization holds both allocated and assigned resources, only the allocation fee applies and the assignment fees are not displayed. If an organization holds multiple resource assignments (ASN, IPv4, and/or IPv6), the invoice details the resource type, quantities, and amount for the annual fee.

Managing Your Fees

Can I combine network registrations so that they are billed as a single network?

Networks may only be combined when they are adjacent to each other. For example: - can be combined with - because the two networks are adjacent. - cannot be combined with - because the two networks are not adjacent. To request that adjacent networks be combined, submit a request through the Ask ARIN link within ARIN Online and specify the adjacent networks you want to combine. This request must be submitted by a registered Admin or Tech POC for the organization.

If I am an ISP, can I return my IPv6 /32 for a /48 to lower my annual fees?

This is not possible under the current policy “Initial Allocation to LIRs,” NRPM 6.5.2.b, as it states that the smallest block an ISP may be allocated is a /36. So the smallest block your organization can reduce to at this time is a /36, which is in the 2X-Small category.

How can I tell if returning IPv6 addresses (or a portion) will reduce my fees?

You will need to look at the Fee Schedule in the Service Category for both IPv4 and IPv6 to determine if returning IPv6 addresses will reduce your fees. Per the current fee schedule, ARIN calculates annual fees based on the larger of your IP address holdings.

For example, if your cumulative (total) IPv4 allocations are greater than a /22 IPv4 allocation (2X-Small) and you have a /32 IPv6 allocation (X-Small), your corresponding Service Category is X-Small, the larger of the two service categories. Returning your /32 for a /36 would reduce your IPv6 Service Category to “2X-Small,” and you will be invoiced according to the fees associated with the 2X-Small Service Category.
