About American Registry For Internet Numbers, LTD.
American Registry For Internet Numbers, LTD., doing business as ARIN, is a tax-exempt, non-profit Regional Internet Registry that provides IP address registration, renewal, and autonomous system number (ASN) management services exclusively as a federal prime contractor, competing under full-and-open procurement with no set-aside designations. Headquartered in Chantilly, Virginia, ARIN operates as a specialized infrastructure service provider delivering narrow but critical technical services to federal agencies' IT and network operations.
ARIN's federal capability footprint is tightly defined: IP address range renewals for IPv4 and IPv6 protocols, autonomous system number registration and management, RPKI-secure routing services, 24/7 customer support portal access, and utilization authority for allocated internet number resources. All 47 awards across the source data are prime contracts (100% of the footprint), nearly all firm fixed-price purchase orders or definitive contracts with annual or multi-year renewal terms and individual ceiling values of $4,410 to $17,640. Representative recent work includes a $17,640 VA Technology Acquisition Center definitive contract awarded August 31, 2026 for IP address renewal and ASN registration services through August 30, 2027; a $16,800 Department of Health and Human Services purchase order awarded November 24, 2025 for HHS IP address range renewal; and a $16,800 Defense Information Systems Agency purchase order awarded September 10, 2025 for ARIN renewal services with completion in April 2026.
Customer concentration reflects ARIN's role as a mandatory service provider to defense and civilian IT infrastructure operators. The top five customer agencies by award count and potential value account for 89% of the awards and 98% of combined potential value. Defense Information Systems Agency dominates with 20 awards and $408 thousand combined potential value, followed by the Department of Veterans Affairs Technology Acquisition Center Austin (11 awards, $128 thousand), Department of Agriculture Office of the Chief Information Officer (7 awards, $78 thousand), Department of Health and Human Services Office of the Assistant Secretary for Administration (3 awards, $49 thousand), and National Oceanic and Atmospheric Administration (1 award, $16 thousand). The rankings track consistently — DISA's share holds across both volume and dollars — reflecting steady, recurring demand for ARIN's services across a fixed set of federal customers.
Activity has grown modestly from two awards in 2022 to five in 2025, with one award in 2026 to date. Four awards with ultimate completion dates in the next twenty-four months carry $56 thousand in combined potential value, indicating recompete opportunity for competitors and renewal exposure for ARIN. ARIN has no subcontractor footprint (zero sub-awards across the source data) and does not sit on any parent vehicles, IDIQs, GWACs, or BPAs — each award is a direct bilateral contract from a federal customer to ARIN. Combined potential value across all 47 awards is $692 thousand, fully obligated, representing subscription-like annual fees for access to ARIN's IP registry services rather than development or modernization engagements.
