.ac
The .ac domain extension is a top-level domain (TLD) primarily used for academic purposes. It's linked to Ascension Island, a remote volcanic island located in the South Atlantic Ocean. However, due to its apt acronym for "academic", it's popularly used by universities, research institutions, and other academic entities worldwide. It's also utilized by academicians and scholars for personal websites. Despite its general association with academia, any individual or organization can register a .ac domain.
