What is .ac TLD

.ac is a country‑code top‑level domain associated with Ascension Island, used internationally for concise, professional naming. We observe .ac domains across research, education, and technology, often selected when academic connotations or short, brandable strings are desirable. In our live index, we track active .ac domains and live .ac websites; notably, already have DNS configured, signalling deployment readiness. Adoption spans countries, showing that .ac websites are not confined to one geography. These baselines let us benchmark growth, detect infrastructure changes, and assess namespace health over time. We combine registration, hosting, and SSL telemetry to quantify the operational footprint of the space. Download .ac domain datasets from webatla for deeper, current visibility.

History and key features of .ac TLD

Introduced as the ccTLD linked to Ascension Island, .ac has evolved beyond locality, with usage patterns shaped by academic shorthand and global technology branding. Core characteristics we monitor include openness of registration, international distribution, and the maturity of active .ac websites. Recent activity remains measured: and indicate steady but selective growth in .ac domains. Combined with countries of use, the namespace demonstrates sustained, diversified adoption. We correlate age, DNS stability, and certificate issuance to understand which .ac websites are enduring versus experimental. These longitudinal signals help organizations evaluate risks, resolve conflicts, and time acquisitions in the .ac TLD. Download .ac domain datasets from webatla to review trends and policy signals.

Why and who choose the .ac domain

Organizations choose .ac for clarity, brevity, and associations with academia, accelerators, and advanced computing. We see .ac domains used by universities, labs, venture and startup programs, and data‑centric firms seeking memorable, globally interpretable naming. Operationally, the proportion of live .ac websites – out of – suggests a meaningful share are in active use, supported by configured records. Cross‑market presence in countries broadens reach while preserving a distinctive TLD identity. Our datasets segment technology stacks, geolocation, and update cadence to surface reliable .ac websites and emerging .ac domains for partnerships, compliance checks, or competitive mapping.
