'''Example.com''', '''example.net''', '''example.org''', and '''example.edu''' are [[Second-level domain|second-level]] [[domain name]]s reserved for documentation purposes and examples of the use of domain names. |
|||
The second level domain label ''example'' for the [[top-level domain]]s <tt>[[.com|com]]</tt>, <tt>[[.net|net]]</tt>, and <tt>[[.org|org]]</tt> was reserved in 1999 by the [[Internet Engineering Task Force]] in RFC 2606, Section 3,<ref>RFC 2606, ''Reserved Top Level DNS Names'', D. Eastlake, A. Panitz, The [[Internet Society]] (June 1999)</ref> while it was reserved for the <tt>[[.edu|edu]]</tt> domain by the [[Internet Corporation for Assigned Names and Numbers]] (ICANN) since 2000. |
|||
By implementing the reservation, the [[Internet Assigned Numbers Authority]] (IANA) made available domains to use in [[technical documentation|technical]] and [[software documentation]], manuals and sample software configurations. Thus, [[Technical writer|documentation writers]] can be sure to select a domain name without creating naming conflicts if end-users try to use the sample configurations or examples verbatim. |
|||
When an address such as ''username@example.com'' is used to demonstrate the sign-up process on a website, it indicates to the user they should fill in an actual [[email address]] at which they receive mail. ''Example.com'' is used in a generic and vendor-neutral manner. |
|||
These domain names resolve to [[Internet Protocol]] (IP) addresses for [[IPv4]] and [[IPv6]] of a [[web server]] managed by [[ICANN]] and are digitally signed using [[Domain Name System Security Extensions|DNSSEC]]. |
|||
The example domains have one subdomain name defined in the [[Domain Name System]]. For each domain, the [[third-level domain]] name ''www'' resolves to the same IPv4 and IPv6 addresses as the parent domains. |
