Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.
The core group of generic top-level domains consists of the [[.com|com]], [[.info|info]], [[.net|net]], and [[.org|org]] domains. In addition, the domains [[.biz|biz]], [[.name|name]], and [[.pro|pro]] are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.
Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains [[.edu|edu]], [[.gov|gov]], [[.int|int]], and [[.mil|mil]] are now considered sponsored top-level domains, much like the themed top-level domains (e.g., [[.jobs|jobs]]). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.
The number of gTLD as of November 2015 exceeds 700 domains, and about 1,900 more are in the waiting list.
