The domain extensions are divided into so-called gTLDs and ccTLDs. The best-known examples of generic top-level domains are, in addition to .com, .net, .org, and .info. For their part, ccTLDs (cc =? Contry code?) Are used as top-level geographic domains, (for example, .es for Spain or .mx for Mexico). Unlike the latter, generic domains must always be composed of at least three letters and, furthermore, a generic top-level domain does not define a geographic location, but rather a subject. Thus, .org denotes an organization and generally refers to non-profit organizations. The gTLD .info emphasizes the informational nature of the web..
During the early years of the Internet, only a few Top Level Domains existed. The first extensions, introduced in January 1985, were. com ,. org ,. net ,. edu ,. gov ,. thousand ,. int and. harp . The first ccTLDs would also be introduced in the same year. There are now hundreds of generic top-level domains as a result of the progressive launch of new gTLDs .
