About the company
American Registry For Internet Numbers, LTD. (doing business as Arin), a non-profit Regional Internet Registry headquartered in Chantilly, Virginia, provides IP address registration, renewal, and autonomous system number management services to federal agencies as a prime contractor on full-and-open purchase orders and definitive contracts, with no subcontract footprint.
Arin operates exclusively as a prime on all 48 of its federal awards across the past two decades, competing in the full-and-open market without set-aside designations. The vendor's concrete service portfolio centers on IPv4 and IPv6 address range renewals, Autonomous System Number registration and management, RPKI-Secure Routing services, and 24/7 customer support access for allocated internet number resources. Recent representative awards include a $17,640 definitive contract from the VA Technology Acquisition Center (August 2026) for annual IP address registration and management services, a $291,060 purchase order from the Defense Information Systems Agency (May 2026) for ARIN renewal services, a $16,800 purchase order from HHS for IP address range renewal (November 2025), and a $4,410 sole-source purchase order from the Government Accountability Office Information Systems and Technology Team (August 2025) for RPKI-Secure Routing services.
Customer concentration is stark. The Defense Information Systems Agency accounts for 44% of all awards (21 of 48) and drives 71% of combined potential value ($699 thousand of $983 thousand total), with the Department of Veterans Affairs Technology Acquisition Center Austin contributing 23% of awards ($128 thousand) and the Department of Agriculture Office of the Chief Information Officer adding 15% of awards ($78 thousand). These three customers represent 90% of Arin's federal award footprint. Arin serves eight distinct federal agencies across all awards, but does not sit on any multi-award IDIQs, GWACs, or government-wide vehicles; each award is a standalone purchase order or definitive contract negotiated directly with the customer agency.
Activity has remained stable and modest — two to five awards per year over the past five years, with the most recent award in August 2026. Combined potential value across the entire portfolio is $983 thousand, fully obligated. Three awards (combined potential value $326 thousand) reach ultimate completion within the next twenty-four months and will require recompete. As a tax-exempt non-profit with a specialized monopoly on regional internet number registry services in North America, Arin's federal customer base reflects subscription-like annual renewals rather than competitive procurements; no competitors appear in the award history or source material.
