What .io is

Technically .io is the country extension of the British Indian Ocean Territory, yet it is used worldwide. Developers read the pair of letters as input/output, and since the mid 2000s the extension has become a standard for startups, APIs, developer tools and documentation.

Registration is open and no connection to the territory is required. The price sits well above general extensions and renewal costs more than the first year, so .io is usually taken for a product that is certain to live rather than kept in reserve.
