Why register a .io domain?
Although the .io domain names have been around since as early as 1997, it is still less common than other generic and extremely popular top-level domains (TLDs). The .io country code domains are an attractive option amongst the tech and startup scene, largely due to the fact that the letters stand for input/output.
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 ideal domain name; a meaningful, unique and concise name may be what it takes to position your business ahead of the competition.
