.ac

.ac is the country-code top-level domain for Ascension Island, a British Overseas Territory in the South Atlantic. IANA lists Internet Computer Bureau Limited as the ccTLD manager.

Direct second-level .ac registrations are internationally accessible. The official registry rules state that an applicant for a second-level .ac domain may reside in any legal jurisdiction, so VYR classifies standard direct registration as open rather than requiring local presence on Ascension Island.

The letters “AC” are also widely recognized in academic, electrical and technology contexts, which has encouraged uses unrelated to the territory. That creative use does not change its technical status as a country-code domain.

The registry has its own acceptable-use rules. In particular, the published .ac rules prohibit use for sexual or pornographic purposes and for activity contrary to statutory law.

A .ac registration also remains subject to reserved-name, technical and third-party-rights requirements. Registrants should review the current registry terms rather than assuming the rules match those of a generic TLD.
