.IO domain name .IO domain name - British Indian Ocean Territory

.IO is the country code domain extension (ccTLD) for the British Indian Ocean Territories, made up of the entire Chagos Archipelgo of 55 islands. Currently, there are no indigenous inhabitants on these islands. They are, however, inhabited by military personnel and civilian contractors from the United Kingdom and United States.

The .IO domain has existed since 1997 but it has never been more popular than it is today, increasingly appealing to individuals and businesses outside of the British Indian Ocean Territories. Associated with Input/Output, .IO is recognisable to those who are web savvy and, therefore, it has become a good way to identify a business with the tech scene. In recent years, it has taken off with startups and tech companies which use the .IO extension to convey the nature of their business, making .IO an excellent marketing tool.

And in today’s crowded online marketplace, every startup needs all the leverage it can get. Registering a .IO domain will provide you with the opportunity to create a domain name that ties in with your branding, giving your website the public face it needs to stand out from the crowd. Capture the essence of your business with .IO. Register yours today!
