The .ac.kr space, while technically a second-level under .kr, serves as South Korea’s academic namespace for accredited institutions. In practice, .ac.kr domains provide verified identities for universities, colleges, and research bodies, while .ac.kr websites deliver admissions, research, and compliance information to domestic and international audiences. We index 1,064 active .ac.kr domains and observe 870 live .ac.kr websites; 870 domains currently resolve via DNS. Usage spans 6 countries, reflecting cross-border hosting and collaborations. This concentrated footprint suggests a mature, institution-driven zone with stable demand and predictable lifecycle patterns. Our datasets surface ownership, nameserver, and technology fingerprints aligned to academic operations and security baselines. Download .ac.kr domain datasets from webatla.
Created within the structured .kr hierarchy, .ac.kr domains have historically been restricted to accredited academic entities, with policy emphasizing institutional legitimacy and operational continuity. This yields a namespace where .ac.kr websites prioritize trust, bilingual communication, and research dissemination, often behind stable DNS and conservative change management. We measure 870 .ac.kr domains with active DNS – closely matching 870 live sites – indicating a deployment pattern oriented to production services rather than speculative holdings, and visibility across 6 countries. Registration flows appear steady rather than expansionary, consistent with the finite pool of eligible institutions and multi‑year domain tenures. Our longitudinal indexing enables comparisons across cohorts, nameserver providers, and hosting geographies. Get our .ac.kr domain datasets at webatla.
Universities, colleges, research institutes, and affiliated academic bodies adopt .ac.kr domains to signal compliance with Korean academic eligibility and to anchor reputation-sensitive services. For users, .ac.kr websites convey institutional credibility, regulatory alignment, and localized support for admissions, grants, and scholarly outputs. Current cadence is stable: we detected 0 new registrations last week and 1 in February 2026, reinforcing a mature, low-churn ecosystem focused on quality operations. With 870 live sites backed by 870 resolving records, most deployments are active rather than parked, and usage appears in 6 countries through global hosting and CDN footprints. We map technologies, DNS health, and lifecycle signals to support benchmarking. Access webatla’s downloadable .ac.kr datasets now.
