.ac.cr is the academic-focused namespace within Costa Rica’s country-code domain system. .ac.cr domains are typically chosen by universities, research bodies, and educational networks to signal affiliation and local presence. In practice, .ac.cr websites convey institutional identity while aligning with national digital policy and governance contexts. From our global crawl, we currently observe active registrations, of which resolve as live sites and present DNS records. Usage spans countries due to cross-border hosting and collaboration, while new registrations last week totaled , indicating a steady, mature zone. We standardize metadata, DNS, and web fingerprints to map this namespace comprehensively. Download .ac.cr domain datasets from webatla.
Like many academic second-level spaces under country codes, .ac.cr emerged to segregate higher-education identities beneath .cr. While formal policy specifics can evolve, .ac.cr domains generally prioritize accredited institutions and research ecosystems, supporting consistent naming conventions and trust cues. In our telemetry, .ac.cr websites exhibit high DNS consistency: have resolvable records, closely matching active domains and live sites. Geographic dispersion across countries reflects hosting choices rather than jurisdictional shifts. Registrations last month were , and last-week additions were , signaling low churn and stable inventories. We track lifespan, server stacks, and content languages to surface durable patterns. Download the .ac.cr domain datasets from webatla.
Universities, colleges, research institutes, and education-adjacent NGOs typically adopt .ac.cr domains to assert academic credibility anchored in Costa Rica’s context. For public outreach, repositories, and departmental portals, .ac.cr websites provide predictable addressing that aligns with peer expectations and citation practices. Decision factors we see include perceived trust, alignment with national education frameworks, and ease of discovery in local search. The namespace remains compact: active domains, live endpoints, and with DNS, distributed across countries. Recent activity is minimal – last week and last month – favoring stability over rapid growth. We curate infrastructure, ownership, and historical snapshots to support due diligence.
