The .IO domain extension has transformed from a simple country code top-level domain (ccTLD) into one of the most sought-after domain choices for tech companies and startups worldwide. Originally designated for the British Indian Ocean Territory, .IO has gained remarkable popularity due to its connection with technology and computing.
Origin and History
The .IO domain was established on September 16, 1997, when the Internet Assigned Numbers Authority delegated it to British entrepreneur Paul Kane along with several other ccTLDs. While technically representing the British Indian Ocean Territory, the domain quickly attracted attention from the global tech community due to its association with “input/output” in computer science.
