New ARIN Fees for 2026: How It Impacts IPv4 Holders

ARIN’s Annual Fee Increase for 2026

ARIN has announced a 5% increase to its Registration Services Plan (RSP) fees, effective for 2026. Approved by the Board of Trustees on April 27, this adjustment is designed to keep ARIN’s operating costs in line with revenues, while enforcing strict cost management practices through 2030.

To provide financial stability and transparency, ARIN continues its policy of capping annual fee increases at 5%—a measure expected to remain in place at least through the end of the decade.

Category	2025 Annual Fees	2026 Annual Fees	IPv4 Block Size	IPv6 Block Size	Number of ASN’s
3X-Small	$262.50	$275.00	/24 or smaller	/40 or smaller	1-3

2026 IPv6 Waiver for 3X-Small Members

A temporary waiver remains in effect for organizations in the 3X-Small category, allowing them to obtain up to a /36 of IPv6 address space without moving into a higher fee tier. The annual cost stays at the 3X-Small level ($262.50 for 2025, $275 for 2026), even if their IPv6 allocation exceeds the typical threshold.

Note: This waiver is set to expire on December 31, 2026. After that, exceeding a /40 of IPv6 space will result in a higher fee category.

No Change to ARIN Transactional Fees for 2026

ARIN’s one-time transactional fees will remain unchanged from 2025. These charges cover specific actions like resource transfers, ASN issuance, and organization updates:

• ASN issuance: $550 per ASN
• ASN annual fee (ASN-only holders): $150
• Organization Create: $50
• Organization Recovery: $100
• Transfer processing (migration, M&A, inter-RIR): $500 (paid by source)
• STLS listing (per listing): $100
• STLS facilitator (annual): $1,000
• Premier Support Plan: $5,000 annually (for XL or smaller organizations)

IPv4 Recipient Transfer Fees: No Updates Since 2023

Recipient (buyer) transfer fees for IPv4 blocks remain consistent with previous years, on a tiered schedule based on block size.

IPv4 Block Size	Recipient Transfer Fee
/24 or smaller	$187.50
/24–/22	$375
/22–/20	$750
/20–/18	$1,500
/18–/16	$3,000
/16–/14	$6,000
/14–/12	$12,000
/12–/10	$24,000
/10–/8	$48,000
/8–/6	$96,000
Smaller than /6	$192,000

What’s the Difference? Annual vs. Transactional Fees

• Annual RSP Fees are recurring charges based on an organization’s total IPv4, IPv6, and ASN holdings. They cover ARIN’s core registry functions and are calculated according to your service category.
• Transactional Fees are one-time costs applied to certain activities—such as transferring address space, ASN assignments, and organizational changes. These are charged only when the specific action occurs.

Plan Ahead: Preparing for the End of the IPv6 Waiver

If your organization relies on the 3X-Small category IPv6 waiver, review your current and future needs before December 31, 2026. Be aware that holding more than a /40 of IPv6 after this date may bump you into a higher fee bracket. Proactive planning can help avoid unexpected costs.
