The .ca.us TLD is the California geographic second‑level within the United States’ .us country code, primarily reserved for public-sector entities and educational institutions. In practice, .ca.us domains identify municipal, county, and K‑12 bodies, while .ca.us websites typically host official services, notices, and records. From our global index, we currently observe active .ca.us domains, with live .ca.us websites and showing DNS configurations. Usage is localized to country, reflecting the namespace’s state‑specific purpose. This concentrated footprint enables precise regional analysis of California’s public digital infrastructure. We continuously standardize ownership signals, name patterns, and resolving status to maintain comparability across civic namespaces. Download the .ca.us domain datasets from webatla.
As a legacy locality subtree of .us, .ca.us emerged early in the commercial internet to provide structured, government‑aligned naming for California jurisdictions. Policies generally prioritize public agencies and schools, so .ca.us domains often follow locality conventions and are administered with stricter eligibility than generic namespaces. Operationally, we see assets with DNS, while only resolve as live .ca.us websites – around 17% of the observed base. Growth is currently subdued: new registrations last week and in our month‑over‑month view. These characteristics suggest stable, low‑churn inventories typical of public sector portfolios. Download historical .ca.us domain datasets from webatla.
Organizations choose .ca.us to signal governmental authority, geographic remit, and compliance with U.S. public‑sector conventions. Typical registrants include cities, counties, school districts, libraries, and special districts, where clarity of jurisdiction matters. For discovery and benchmarking, we surface ownership fingerprints, hosting shifts, and redirects across .ca.us domains and comparable civic namespaces. Today we track assets in scope, with operational .ca.us websites and usage confined to country, illustrating a focused, California‑specific ecosystem. Procurement teams and researchers can use these signals to map services, monitor consolidation, and audit digital continuity across agencies.
