測試時可使用的保留 domain name
« 於: 2001-06-28 10:55 »
簡單的意思就是:

如果你要測試 domain name 的話,可以使用 example.com, example.net,example.org

According RFC 2606

1.Reserved Top Level DNS Names:

four domain names are reserved as listed and described below.

    .test
    .example
    .invalid
    .localhost

    ".test" is recommended for use in testing of current or new DNS related code.

    ".example" is recommended for use in documentation or as examples.

    ".invalid" is intended for use in online construction of domain names that are sure to be invalid and which it is obvious at a glance are invalid.

    The ".localhost" TLD has traditionally been statically defined in host DNS implementations as having an A record pointing to the loop back IP address and is reserved for such use.

    Any other use would conflict with widely deployed code which assumes this use.

2.Reserved Example Second Level Domain Names

The Internet Assigned Numbers Authority (IANA) also currently has the following second level domain names reserved which can be used as examples.

    example.com
    example.net
    example.org
