Additional Reserved Top Level Domains

Metadata

Publisher: IETF
Doc Type: Standard
Abstract: The Internet Domain Name System (DNS) defines a tree of names starting with root, ".", immediately below which are top level domain (TLD) names such as ".com" and ".us". In June 1999 reserved a small number of TLD names for use in documentation examples, private testing, experiments, and other circumstances in which it is desirable to avoid conflict with current or future actual TLD names in the DNS. There has been significant evolution of Internet engineering and operation practices since was published. In February 2013 defined criteria and procedures for reserving a domain name for special use, and established an IANA registry for such names. This document reserves three domain name labels for special use in accordance with the criteria and procedures of : home, corp, and mail. It is important to note that TLD names may be reserved, in other contexts, for policy, political, or other reasons that are distinct from the IETF's concern with Internet engineering and operations. This document reserves TLD names only for operational and engineering reasons.
