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.

What criteria are used to determine my fee?

ARIN determines fees per Org ID. End user or assigned resource fees are determined by type (resource handle) and the number of assignments held. ISP or allocated resource fees are assessed by cumulative size, and 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" of my IPv4 allocations?

The current fee schedule is based on the total amount of IP address space a company holds that is covered under an ARIN Registration Services Agreement (RSA).  For 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 is calculated solely on your ARIN issued space and falls under the small Service Category of the fee schedule.


If I was approved for resources in June but don't pay until July, will my fees be based on the previous Fee Schedule or the current Fee Schedule?

ARIN assesses fees as of the resource request approval date. If ARIN approved your organization for resources in June, the former fee schedule applies. If your organization received approval from ARIN on or after 1 July 2013, your fees are based on the current fee schedule.

In previous years, I received a consolidated invoice for my ARIN-issued and Legacy number resources, why did this change?

ARIN separated the billing for resources held under a Registration Services Agreement (RSA) and Legacy Registration Services Agreement (LRSA) due to the difference in applicable terms. Organizations that have both a RSA and a LRSA with ARIN will receive an invoice for the resources held under the RSA and a separate invoice for the resources held under LRSA. Organizations desiring consolidated billing should move their resources under a single Registration Services Agreement.

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/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 X-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 /19 and you have a /32 IPv6 allocation; you are in the "Small" Service Category.  Returning your /32 for a /36 would reduce your IPv6 Service Category to "X-Small", but you will still be billed in the "Small" Service Category because your total IPv4 holdings are larger than a /19, which falls under the Small category.  

Changes to the Fee Schedule

When was the current Fee Schedule implemented?

The current fee schedule went into effect on 1 July 2013. It was approved by the Board of Trustees on 7 January 2013 and announced to the community on 20 February 2013.

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
  • Meet the community's expectations for new and future services such as RPKI
  • Maintain and reduce, where possible, cost for smaller ISPs
  • Provide a revenue model based on long-term expenses

How did fees change between the current version of the Fee Schedule and the prior one?

The changes included:

    • Aligning the IPv4 and IPv6 fee schedules for ISPs into a single set of registration services plans based on total resources held
    • Per address block and per ASN maintenance fees for end-users
    • A new, very low-cost category (e.g. XX-Small) for the smallest organizations.
    • Transfer fees have increased and associated costs have been clarified

I transferred a direct allocation and was previously being billed a $100 annual maintenance fee but am now being charged the ISP annual renewal fee. What changed? How can I correct the billing, I'm not an ISP?

Under the previous fee schedule, the annual ISP renewal fee for transferred direct allocations was assessed only when ARIN could verify the organization was an ISP. Under the new fee schedule, implemented July 1, 2013, the ISP annual renewal fee is assessed to all organizations with direct allocations.

Reassignments are prohibited for organizations seeking to convert from a direct allocation to a direct assignment. Organizations, with direct allocations having reassignments, that are not ISPs should use ARIN Online to remove those reassignments. Organizations with direct allocations, without reassignments, may contact ARIN by sending an Ask ARIN request from their ARIN Online account to request their direct allocations be converted to direct assignments. If approved, this will allow the organization to be billed the end user annual maintenance fee rather than the ISP annual renewal fee.
