Internet Best Domains

This is a list of Internet top-level domains (TLDs). A top-level domain is a domain name in the Domain Name System that is a direct subdomain of the DNS root zone.

 The official list of all top-level domains is maintained by the Internet Assigned Numbers Authority (IANA).

 In an initiative to expand the domain name space, IANA is considering approval of several proposed top-level domains.

Original top-level domains

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

•  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	Notes	IDN	DNSSEC
.com	commercial	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".	Yes	Yes
.org	organization	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	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	The .int TLD is strictly limited to organizations, offices, and programs which are endorsed by a treaty between two or more nations. However, there are a few grandfathered domain names that do not meet these criteria.	No	No
.edu	educational	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 US colleges and universities. Some institutions that do not meet the current registration criteria have grandfathered domain names.	No	Yes
.gov	governmental	The .gov TLD is limited to governmental entities and agencies in the US.	No	Yes
.mil	US military	The .mil TLD is limited to use by the US military.	No	Yes
