What is Generic Top-Level Domain (gTLD)?
A generic top-level domain (gTLD) is a top-level domain category (TLD) that is easily recognized by a suffix attached to a domain name. These are used by the Internet's Domain Name System (DNS) and monitored by the Internet Assigned Numbers Authority (IANA), which is now controlled by the Internet Corporation for Assigned Names and Numbers (ICANN).
Examples of well-known gTLDs are com, org, info, net and biz. Generic and restricted TLDs created during the early DNS days require proof of eligibility to register domain names. These TLDs are gov, mil, int, and edu.
In 2012, ICANN implemented a gTLD expansion program that launched many new gTLDs that were perceived as more of a nuisance than a way of opening up the Internet to new creative possibilities. New TLDs like 'Ninja' and 'Unicorn' are examples of this. Esther Dyson, an ICANN co-founder, stated that this expansion creates jobs for marketers and lawyers, but provides minimal additional value.
