.io was originally assigned as the ccTLD for British Indian Ocean Territory but has become one of the most popular domain name extensions for startups. .io operates a DNSSEC signed zone, operated on a secure, globally diverse anycast system with over 40 locations. Your domain will work securely, as expected, and fast!


Benefits of Using a .io

  • In the tech and software development world, i/o means input/output, so .io is particularly relevant to that audience.
  • .io is shorter than three-letter gTLDs, while being different, which makes it easy to remember.

Special Requirements

There are no special requirements or restrictions on who may register a .io.
