What Fees Does ARIN Charge and How Does Billing Work?
ARIN (American Registry for Internet Numbers) is a nonprofit, member-based organization that administers IP addresses and Autonomous System Numbers (ASNs). If you hold or plan to request Internet number resources from ARIN, you will encounter registration and maintenance fees, and you pay them through ARIN's online billing system. The exact amount depends on the type and size of the resources you hold, so the authoritative source is always ARIN's current Fee Schedule. Below is how the pieces fit together.
What ARIN charges for
ARIN's fees fall into a few broad categories:
- Registration and maintenance fees for Internet number resources — IPv4 addresses, IPv6 addresses, and ASNs. These are tied to the resources you hold, not to a one-time purchase.
- Fee Schedule — the single reference document that lists the amounts and tiers. ARIN publishes it under "Fee & Billing Information."
- Premier Support Plan (PSP) — an optional support plan that sits alongside the standard fee structure.
- Payment processing — ARIN provides a "Make a Payment" / "Pay Now" path for settling invoices.
Because the amounts are tiered by resource type and size, this article does not quote specific dollar figures. Check the Fee Schedule for current numbers before you budget.
How billing works
ARIN's billing is organized around your organization's resource holdings and account:
- You hold resources under an ARIN account. Registration and maintenance fees are assessed against that account.
- ARIN issues invoices according to its billing cycle. The "How Billing Works" page under Fee & Billing Information explains the mechanics.
- You pay online through the Make a Payment / Pay Now option.
- If resources change — you return them, transfer them, or they are revoked — billing adjusts accordingly. ARIN documents this under "Resource Revocation, Returns, and Reinstatement."
A practical point: fees are recurring maintenance obligations, not a one-time charge. If you transfer IP addresses or ASNs in or out, or return resources, your ongoing fees change with your holdings.
Paying your ARIN bill
ARIN offers an online payment path:
- Make a Payment — https://www.arin.net/resources/fees/payment/
- Pay Now — https://www.arin.net/resources/fees/payment
Both point to the same payment area. To pay, you need access to the ARIN account associated with the invoice. ARIN's site notes that requests and account functions are subject to terms of use, and account management happens through ARIN Online.
Optional: Premier Support Plan (PSP)
The Premier Support Plan is listed alongside the standard fee and billing information. It is an optional plan, so treat it as an add-on decision rather than a default charge. If you need a higher level of support than standard, review PSP terms against your needs.

Common questions
Is ARIN free? ARIN is a nonprofit, but it charges registration and maintenance fees for the resources it administers. Do not assume resource holding is free — check the Fee Schedule.
Do I pay once or repeatedly? Maintenance fees recur based on the resources you hold. Budget for ongoing cost, not a single payment.
What if I return resources? Billing is tied to your holdings, so returns and revocations affect what you owe. See ARIN's revocation, returns, and reinstatement guidance.
Can I pay without logging in? ARIN's payment pages are part of its account system. Plan on using your ARIN Online account to manage and pay invoices.
For any figure you need to act on, go to ARIN's Fee Schedule and How Billing Works pages — those are the sources that stay current.
