Top level domain list

Original top-level domains[edit]

Seven generic top-level domains were created early in the development of the Internet, and pre-date the creation of ICANN in 1998.^[2]

• Name: DNS name
• Entity: intended use
• Notes: general remarks
• IDN: support for internationalized domain names (IDN)
• DNSSEC: presence of DS records for Domain Name System Security Extensions

Name	Entity	Administrator[3]	Notes	IDN	DNSSEC
.com	commercial	Verisign	This is an open TLD; any person or entity is permitted to register. Though originally intended for use by for-profit business entities, for a number of reasons it became the "main" TLD for domain names and is currently used by all types of entities including nonprofits, schools and private individuals. Domain name registrations may be successfully challenged if the holder cannot prove an outside relation justifying reservation of the name, to prevent "squatting". It was originally administered by the United States Department of Defense.	Yes	Yes
.org	organization	Public Interest Registry	This is an open TLD; any person or entity is permitted to register. Originally intended for use by non-profit organizations, and still primarily used by some.	Yes	Yes
.net	network	Verisign	This is an open TLD; any person or entity is permitted to register. Originally intended for use by domains pointing to a distributed network of computers, or "umbrella" sites that act as the portal to a set of smaller websites.	Yes	Yes
.int	international organizations	Internet Assigned Numbers Authority	The .int TLD is strictly limited to organizations, offices, and programs which are endorsed by a treaty between two or morenations. However, there are a few grandfathered domain names that do not meet these criteria.	No	No
.edu	U.S. higher education	Educause (viaVerisign)	The .edu TLD is limited to specific educational institutions such as, but not limited to, primary schools, middle schools, secondary schools, colleges, and universities. In the US, its usability was limited in 2001 to post-secondary institutions accredited by an agency on the list of nationally recognized accrediting agencies maintained by the United States Department of Education. This domain is therefore almost exclusively used by American colleges and universities. Some institutions that do not meet the current registration criteria have grandfathered domain names.	No	Yes
.gov	U.S. national and state government agencies	General Services Administration (viaVerisign)	The .gov TLD is limited to governmental entities and agencies in the U.S.	No	Yes
.mil	U.S. military	United States Department of Defense	The .mil TLD is limited to use by the United States military.	No	Yes

Infrastructure top-level domain[edit]

Infrastructure	Entity	Notes	IDN	DNSSEC
.arpa	Address and Routing Parameter Area	Originally assigned to the Advanced Research Projects Agency in the early days on the Internet, .arpa is now exclusively used as an Internet infrastructure TLD.	No	Yes

Country code top-level domains[edit]

Note: the country code domain system was created in the early days of the Domain Name System, and pre-dates ICANN.

• Name: DNS name of the (ISO 3166-1 alpha-2) two-letter country-code top-level domain
• Entity: country, dependency, or region
• Explanation: explanation of the code when not self-evident from the English name of the country
• Notes: general remarks
• IDN: support for internationalized domain names (IDN)
• DNSSEC: presence of DS records for Domain Name System Security Extensions
• SLD: allows Second-level domain registration (restrictions may apply)
• IPv6: Registry fully supports IPv6 access
