Reserved top-level domain
Reserved to prevent conflict and confusion
In documentation or for internal testing
Those using it for testing can use it in any desired structure
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. [1 ]
Reserved DNS names [ edit ]
In 1999, the
Internet Engineering Task Force reserved the DNS labels , example , invalid , and localhost 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. [1 ]
