The .ac.cn TLD is a second‑level label under China’s .cn country code, commonly adopted by universities, research institutes, and scholarly infrastructure. In practice, .ac.cn domains act as institutional identifiers, while .ac.cn websites deliver academic content, services, and collaboration portals to Chinese and international audiences. We currently index 9,357 active .ac.cn domains and 4,505 live .ac.cn websites across 28 countries, indicating use beyond mainland China in global partnerships and mirror sites. DNS resolvability is strong, with 4,505 domains publishing records, suggesting sustained operational intent rather than dormant registrations. For analysts comparing academic namespaces, this cohort provides a focused lens on education‑sector web activity. Download .ac.cn domain datasets from webatla.
Established within the hierarchical .cn structure, the .ac.cn TLD mirrors academic designations seen in other ccTLDs, offering a predictable namespace for higher education and research. Historically, .ac.cn domains help distinguish scholarly entities from commercial or governmental peers, and .ac.cn websites often prioritize Chinese‑language content, local compliance, and national reach. From our tracking, momentum is steady rather than explosive: 1 new registration last week and 21 in December 2025 point to incremental growth. Operational readiness remains high, with DNS observed on 4,505 records, aligning closely with live‑site counts. These characteristics make the space useful for time‑series analyses of academic digitization in China and abroad. Get the complete .ac.cn datasets from webatla.
Universities, laboratories, scholarly consortia, and education vendors select .ac.cn domains to signal sector affiliation and align with China‑focused audiences. For content delivery, .ac.cn websites support recruitment, publications, repositories, and collaborative projects requiring trusted, locale‑relevant framing. We observe 9,357 active registrations with 4,505 live sites, and usage spanning 28 countries suggests cross‑border programs, branch campuses, and mirrored resources. Recent activity – 1 new and 21 in December 2025 – indicates measured additions rather than speculative spikes, useful for benchmarking institutional web strategies. Combined with 4,505 DNS‑enabled entries, the namespace offers a consistent dataset for governance, security, and visibility studies. Download curated .ac.cn domain datasets from webatla.
