What is .ac.se TLD
The .ac.se TLD denotes a focused namespace commonly associated with academic and institutional use within Sweden. In our global index, we track .ac.se domains and .ac.se websites alongside other structured spaces to understand visibility, resilience, and governance patterns. Today we observe 15 active registrations, with 6 showing configured DNS, and 6 resolving as live websites. Usage concentrates in 1 country, reflecting a geographically specific mission despite the global reach of our crawlers. These signals suggest a small, curated zone where DNS configuration and web presence move together. We continuously monitor naming churn, server footprints, and content signals to surface risk and opportunity for researchers, registrars, and security teams.

History and key features of .ac.se TLD
The history of the .ac.se TLD aligns with the evolution of sector-specific naming under national registries, emphasizing stability and clear eligibility. In practice, .ac.se domains and .ac.se websites tend to appear in conservative growth cycles shaped by institutional procurement and compliance. Our recent crawl shows 0 new registrations last week and 0 in November 2025 overall, consistent with a low-volatility namespace. Out of 15 observed domains, 6 publish DNS, indicating active configuration discipline; many of these surface as 6 accessible websites. Such ratios help forecast future resolution rates, detect parked assets, and prioritize monitoring. We correlate hostnames, ASN movement, and certificate changes to map operational continuity.

Why and who choose the .ac.se domain
Organizations choose the .ac.se TLD when alignment with Swedish academic or institutional identity is important, and when audience trust benefits from predictable governance. Stakeholders evaluating .ac.se domains and .ac.se websites typically include university web teams, research consortia, library networks, cybersecurity groups, and public-sector IT buyers. The footprint remains focused: 1 country accounted for active use in our latest pass, with 6 live websites detectable out of 15 total domains. Such concentration favors clear branding, simpler threat modeling, and benchmarking of content updates, TLS policies, and mail security adoption. We segment the zone by hosting provider, CMS fingerprint, and DNS hygiene to reveal operational baselines and outliers. Download webatla’s .ac.se data to benchmark presence and track changes.
