What Does .io Mean and What is the .io Domain Extension?

You’re probably familiar with the term TLD, but what is a TLD and what exactly does it stand for? The term TLD stands for top-level domain and refers to the ending of a domain name, or the section that immediately follows the dot symbol, such as .com, .net, .org, .edu, and others. You’ve almost certainly seen the plethora of country-specific TLDs (also known as a country code top-level domain, or ccTLD), such as .fr, .ca, or .co.uk. And you probably know that there are scads of other generic top-level domains (known as gTLDs), such as .inc, .business, and, yes, even .xxx. According to Internet Assigned Numbers Authority (IANA), there are currently more than 1,500 TLDs.
