What is .fed.us TLD
The .fed.us space is a restricted second-level namespace within the .us country-code domain, reserved for U.S. federal government entities and their programs. In our taxonomy, .fed.us domains identify authoritative government-owned assets, while .fed.us websites deliver public-facing services, documentation, and data. Use typically complements .gov naming for departments, labs, and interagency initiatives where legacy systems or specialized routing persists. We currently index active .fed.us domains; our live-website counter reports , and DNS visibility covers hosts, with usage observed across countries. These figures update as we crawl, validate registrant eligibility, and reconcile decommissioned endpoints. To explore entity-level detail, technology stacks, and lifecycle trends, we provide downloadable datasets curated from continuous scans. Download comprehensive .fed.us datasets from webatla.
History and key features of .fed.us TLD
Historically, the .fed.us label emerged from the early structuring of the usTLD, segmenting government and locality namespaces before widespread consolidation on .gov. Today, .fed.us domains often persist for legacy portals, research infrastructure, or controlled-access services, while .fed.us websites may redirect, coexist, or serve niche communities. Eligibility is restricted to federal bodies; growth is limited and subject to administrative policy and technical governance within the usTLD. In our corpus, new registrations are modest: last month and last week. We inventory active objects and observe live sites with demonstrating DNS responsiveness. These metrics are normalized for duplicates and parked hosts. Get the latest .fed.us domain datasets from webatla.
Why and who choose the .fed.us domain
Organizations selecting this label typically include federal departments, national laboratories, interagency task forces, and legacy program offices. They choose .fed.us domains for continuity, namespace control, and alignment with historical routing, while .fed.us websites emphasize stability, archival access, or specialized communities rather than broad branding. Decision drivers include compliance posture, DNS delegation needs, and the cost of migration to .gov alternatives. From an operational perspective, we see domains with DNS records and usage across countries, against a base of active registrations and live endpoints. Short-term onboarding remains low, with observed last week in our deltas. Download webatla’s .fed.us domain datasets now.
