.ac domain extension

.ac is the country code top-level domain for Ascension Island, a British Overseas Territory in the South Atlantic. It is managed by Internet Computer Bureau Limited, based in the UK. The registry is open to anyone, with no specific local presence requirements, making it popular for academic and technology uses due to its abbreviation for 'academic.' Registration is handled through accredited registrars listed at nic.ac. The domain was delegated on December 19, 1997, and has been operated by the same sponsor since then.
