.ac
A .ac domain is the country code domain for Saint Helena, Ascension and Tristan da Cunha, which is a British Overseas Territory in the South Atlantic. The registry is run by Internet Computer Bureau Limited, and its own website is nic.ac.
The .ac extension has no registration restrictions, and it supports DNSSEC, which helps protect your domain from certain kinds of tampering. Names can be between 3 and 63 characters long. Internationalised names are not allowed, so your domain must use standard characters. Individuals can ask the registry to hide their contact details from public view.
A .ac domain is a good choice if you want a short, memorable address for a personal website or email. Academia has eagerly adopted it, so students and teachers often use it. Before you register, check that the name length and character rules suit the name you want.
