What is a .ac domain and why use it?

.ac is the domain name extension specifically designated for Ascension Island, a remote location in the South Atlantic Ocean. However, it is also widely used by academic institutions, particularly higher education and research organizations, due to its association with the term 'academic.' This extension is managed by the Internet Computer Bureau. Potential use cases for .ac domains include university websites, research hub portals, academic organization platforms, and educational resource sites.
