The .ac top-level domain is the Internet country code (ccTLD) for Saint Helena, Ascension and Tristan da Cunha, and primarily for Ascension Island. It is administered by NIC.AC, a subsidiary of the Internet Computer Bureau based in the United Kingdom.
Registration for the domain is open to anyone. The registry accepts registrations of internationalized domain names.[1]
The domain is marketed by some domain-brokers as a domain for the city of Aachen, Germany, after the automotive license plate designation ("AC") for the city.
Use as an abbreviation for "academic"[]
Due to its similarity to the .ac ("academic") second-level domain that exists under some country code top-level domains, some educational institutions also register under the .ac top-level domain:
- The University of Kurdistan - Hawler[2]
- Ralston College in Savannah, Georgia, United States[3]
- in Edinburgh, Scotland[4]
- It is also used for promotion, campaigns, and URL shortening by various parts of the University of Edinburgh, Scotland[5][6]
- The (MORU) in Bangkok, Thailand[7]
- INFORM (Information Network Focus on Religious Movements), based at the London School of Economics[8]
- Newcastle University, an online university unconnected with Newcastle University in the United Kingdom or the University of Newcastle, Australia[9]
