Why register a .io domain?

Although the .io domain names have been around as early as 1997, it is still less occupied than other generic and extremely popular top-level domains (TLDs). TLDs with the .io country code are an attractive option amongst the tech and startup scene and this is largely due to the fact that the letters stand for input/output within the industry.

Input/output represents the fundamental concept of computers: every input results in an output. Businesses, companies and individuals alike can benefit from the creative freedom of choosing their favored domain name; a meaningful, unique and concise name may be what it takes to position your business ahead of the competition.

What does the .io domain ending stand for?

Despite its popularity amongst the tech industry, where the .io domain meaning is commonly known as an abbreviation for input/output, the .io domain name in fact stands for the Indian Ocean. As with all domain names, each country or territory is assigned its own two-letter country code. Other country code top-level domains (ccTLDs) include, for example, .ca for Canada and .co.uk for the United Kingdom.

In recent years, it is not only the tech and startup industry that has been taking advantage of the catchy country code level, but also brands or words that are complemented by the .io domain name such as www.aud.io or wwww.mustach.io. This has naturally resulted in fewer businesses actually operating in the British Indian Ocean Territory availing of this specific domain name. It has therefore become less of a representation of the British Indian Ocean, and more of a generic TLD.
