.test

The name test is reserved by the Internet Engineering Task Force (IETF) in RFC 2606 (June 1999) as a domain name that is not intended to be installed as a top-level domain (TLD) in the global Domain Name System (DNS) of the Internet for production use.

Reserved DNS names

In 1999, the Internet Engineering Task Force reserved the DNS labels example, invalid, localhost, and test so that they may not be installed into the root zone of the Domain Name System.

The reason for reservation of these top-level domain names is to reduce the likelihood of conflict and confusion. This allows the use of these names for either documentation purposes or in local testing scenarios.

Types

As of 2015, IANA distinguishes the following groups of top-level domains:

List of Internet top-level domains

This list of Internet top-level domain extensions contains all top-level domains, which are those domains in the DNS root zone of the Domain Name System of the Internet.

The official list of all top-level domains is maintained by the Internet Assigned Numbers Authority (IANA). IANA also oversees the approval process for new proposed top-level domains. As of January 2016, the root domain contains 1205 top-level domains, while a few have been retired and are no longer functional.

Types

As of 2015, IANA distinguishes the following groups of 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.

Genetic relationship (linguistics)

In linguistics, genetic relationship is the usual term for the relationship which exists between languages that are members of the same language family. The term genealogical relationship is sometimes used to avoid confusion with the unrelated use of the term in biological genetics. Languages that possess genetic ties with one another belong to the same linguistic grouping, known as a language family. These ties are established through use of the comparative method of linguistic analysis.

Two languages are considered to be genetically related if one is descended from the other or if both are descended from a common ancestor. For example, Italian is descended from Latin. Italian and Latin are therefore said to be genetically related. Spanish is also descended from Latin. Therefore, Spanish and Italian are genetically related. In a similar way, Swedish and Norwegian are genetically related through the North Germanic branch of the Indo-European language family.
