.k12.ca.us is a structured public-sector domain space within .ca.us dedicated to California’s K–12 institutions. We index .k12.ca.us domains and .k12.ca.us websites to map the footprint of school districts, charters, and education agencies. Our current index reports active domains and live websites, with activity observed across countries based on hosting and usage signals. Growth is minimal and tightly governed; we recorded new registrations last week. This combination of scope and stability makes the namespace useful for policy analysis, vendor discovery, and attack-surface monitoring across the education sector. Download the .k12.ca.us domains dataset from webatla now.
The .k12.ca.us namespace emerged under the .us locality hierarchy to standardize public-school online identities in California; eligibility typically requires affiliation with recognized K–12 authorities. For researchers tracking .k12.ca.us domains and .k12.ca.us websites, key features include consistent naming conventions, clear geographic anchoring, and relatively static portfolios. Operational signals are strong: we see domains with DNS records, closely aligned with the live website count. Recent issuance remains subdued – – reflecting mature, policy-led administration rather than market-driven churn. These characteristics support longitudinal studies of service providers, technology stacks, and security posture across districts and counties. Get our historical .k12.ca.us domains dataset from webatla today.
Organizations choosing this space are primarily public school districts, county offices of education, charter networks, and cooperative service bodies; some vendors also host official .k12.ca.us websites on behalf of clients. They prefer it for trust, alignment with public-sector identity, and procurement compliance. Analysts profile .k12.ca.us domains to map infrastructure, detect third‑party dependencies, and benchmark adoption of critical web services. Our dataset covers registered assets, live websites, and DNS-enabled domains, with activity visible in countries despite localized policy scope. New additions are infrequent (; ), so longitudinal comparisons remain robust. Download webatla’s .k12.ca.us domains and websites dataset for deeper analysis.
