AMERICAN REGISTRY FOR INTERNET NUMBERS, LTD.

American Registry for Internet Numbers, Ltd. specializes in the management and allocation of Internet number resources, including IPv4 and IPv6 address blocks and Autonomous System Numbers (ASNs), under standardized registration services frameworks. The contractor provides critical infrastructure support to federal agencies by maintaining accurate, secure, and policy-compliant registries for IP address assignments and routing autonomy. Their technical expertise lies in Internet governance protocols, RIR (Regional Internet Registry) operations, and adherence to the Registration Services Plan (RSP), ensuring compliance with global Internet numbering standards. Key differentiators include deep familiarity with IETF and ICANN-aligned policies, robust resource verification processes, and scalable systems for managing large-scale IP allocations across diverse federal networks. The contractor delivers these services to multiple departments across the federal landscape, including the Department of Justice, Department of Health and Human Services, Department of Veterans Affairs, Department of Defense, and Department of Commerce. Each agency relies on ARIN for the renewal and expansion of IP address resources essential to mission-critical systems, network modernization, and secure communications infrastructure. Relationships are consistent and recurring, indicating trusted, long-term operational partnerships grounded in regulatory compliance and technical reliability. The primary NAICS code, 519290, reflects the contractor’s focus on Internet information services, specifically the administration of digital identifier resources rather than content delivery or web portals. This positions them as a foundational enabler in the federal IT ecosystem, serving as a trusted intermediary between global Internet numbering authorities and agency network operations. Their secondary NAICS, 517810, further underscores their role in telecommunications infrastructure support through resource provisioning. As an 8H-certified entity headquartered in Chantilly, Virginia, the contractor operates as a small business with a specialized, mission-critical niche in federal Internet infrastructure. While no additional certifications are listed, their operational credibility stems from institutional expertise in Internet number resource management and sustained engagement with high-stakes federal networks.
