Generic Top-Level Domain

What Does Generic Top-Level Domain Mean?

A generic top-level domain (gTLD) is a top-level domain (TLD) category that is easily recognized by a suffix attached to a domain name. These are used by the Internet’s Domain Name System (DNS), with oversight by the Internet Assigned Numbers Authority (IANA), which is now controlled by the Internet Corporation for Assigned Names and Numbers (ICANN).

Examples of 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 for domain name registration. These TLDs are gov, mil, int and edu.

In 2012 ICANN implemented a gTLD expansion program, which launched many new gTLDs that have been perceived as an annoyance, rather than a way to open the Internet to new creative possibilities. New TLDs, like "ninja" and "unicorn," are examples. Esther Dyson, an ICANN co-founder, stated that this expansion will create jobs for marketers and lawyers but serve minimal additional value.
