On February 4, you'll be able to get Internet domain names with such new generic top-level domains (gTLDs) names as .CHEAP, .NINJA, or .SEXY. So, yes, if you really wanted to, you could have such domain names as dirt.cheap, joethe.ninja or imvery.sexy. Ack!
GTLDs are part of the Domain Name System (DNS). They're the last label of fully qualified domain names such as .com, .edu, and .gov. These are used to give human-readable addresses to the Internet's cryptic IPv4 and IPv6 addresses. So far, so good.
