Generic top-level domain
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 level of every fully qualified domain name. They are called generic for historical reasons; initially, they were contrasted with country-specific TLDs in RFC 920.
|Historical generic TLDs|
||Mainly for commercial entities, but unrestricted|
||Originally for organizations not clearly falling within the other gTLDs, now unrestricted|
||Originally for network infrastructures, now unrestricted|
||Educational use, but now primarily for third-level colleges and universities|
||Governmental use, but now primarily for US governmental entities and agencies|
||Military use, but now primarily for US military only|

The core group of generic top-level domains consists of the
info domains. In addition, the domains
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
mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g.,
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.
