'''Generic Top Level Domains''' ('''gTLDs''') are [[TLD]]s with three or more characters.  Generally speaking, an unsponsored gTLD [[Registry]] operates under policies established by the global Internet community directly through the [[ICANN]] process. .biz, .com, .info, .name, .net, .org, and .pro are [[unsponsored TLD]]s. [[.asia|.Asia]] is an example of a sponsored TLD.
A '''Generic Top Level Domain''' ('''gTLD''') is one of the top level domains ([[TLD]]) in the Domain Name System ([[DNS]]) maintained by the Internet Assigned Numbers Authority ([[IANA]]). There are 21 gTLDs in the root zone of the internet and they are categorized as:<ref>[http://www.iana.org/domains/root/db/# IANA Root Zone Data Base]</ref>
* '''generic''' ([[.com]],[[.info]], [[.net]], [[.org]]) which can be used for general purposes;
* '''sponsored,''' ([[.aero]], [[.asia]], [[.cat]], [[.coop]], .edu, .gov, .int, .jobs, .mil, .mobi, .tel and .travel) which can only be used by entities engaged within the specific industry;
* '''generic restricted'''(.biz, .name, .pro) which can be use only for their specified purposes and
* '''infrastructure'''(.arpa) is exclusively used to support operationally-critical infrastructural identifier spaces and it is operated by IANA.
 
The gTLDs are managed and operated by their sponsor organizations and registry operators that were approved by the [[ICANN|Internet Corporation for Assigned Names and Numbers]].

Going forward, TLDs will be identified as either "open" or "community."
