Fee Schedule FAQ

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 AS Numbers (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.

Please refer to the applicable section of the 2016 Fee Schedule to determine which option is best for your organization.


Where do I find more information on the billing process?

The Annual Billing, Invoice Reminder, Revocation and Reinstatement process is outlined 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 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. 

Changes to the Fee Schedule

When was the current fee schedule implemented?

The current fee schedule was implemented on 1 July 2016. It was approved by the Board of Trustees on 10 December 2015 and announced to the community on 14 March 2016.

A revision of the Resource Transfer section of the Fee Schedule arose out of a community consultation regarding a proposal from the Board of Trustees. After approval by the Board, this change was announced to the community on 19 December 2016 and implemented on 1 January 2017.

Why was the fee schedule changed?

The ARIN Board of Trustees adopted the current fee schedule in order to:

  • Ensure members receiving comparable services are paying comparable fees where feasible
  • Maintain and reduce, where possible, cost for smaller ISPs
  • Provide a revenue model based on long-term cost recovery

The Resource Transfer fees were later amended, following a community consultation, in order to encourage organizations to only submit bona fide requests, and serve to reduce transfer processing fees for all legitimate requests.

How did fees change between the 2016 version of the fee schedule and the previous one?

The changes include:

  • Creation of four (4) new service categories; 3X-small, 3X-large, 4X-large, and 5X-large; these are intended to further recover ARIN’s costs across a broader set of service categories which more closely align with the benefits received
  • Realignment of the IPv6 and IPv4 resource limits for each category to provide for more cost-effective IPv6 usage
  • End-user organizations may now choose to receive ARIN services via a Registration Services Plan (the same services and fee package provided to ISPs) – those which do so become ARIN Members (with associated voting rights in ARIN elections) as well as the capability to report reassignment information and/or provide utilization data via the Shared Whois Project (SWIP)

These changes further balance overall fees so that customers receiving comparable services are paying comparable fees where feasible, and also enable a reduction in many cases to the fees for smaller ISPs.

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 Merger, Acquisition, and Reorganization 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.
