British Indian Ocean Territory
Overview
Few extensions have drifted further from their assigned territory than .io, the country code of the British Indian Ocean Territory. Administered by Internet Computer Bureau Ltd since 1997, it holds approximately 1.5 million domains, the overwhelming majority registered by software companies. The reason is a coincidence of abbreviation: in computing, I/O denotes input and output. Developer tools, APIs, and software-as-a-service products adopted the extension early, and registration remains open worldwide.
