IDN support in .nz ================== The registration of IDNs (internationalised domain names) with macronised vowels which feature in the Māori language, an official language under New Zealand law, has been permitted in the .nz name space since July 2010. Domain names are allowed to consist of 26 basic English (Latin) alphabet characters a-z, digits, the '-' hyphen, and characters ā, ē, ī, ō and ū. In addition to the extra characters for registrations the second level māori.nz (with the ā macron) is provided as a mirror of the maori.nz 2LD using the DNS feature called DNAME. This ensures that all existing and future names registered under maori.nz are duplicated in the DNS under māori.nz. .nz Latn --------- The following character table is called nz Latn and contains the characters used by InternetNZ for the registration of .NZ domains represented using the Latin script. `IANA nz Latn Table `_ The table lists the Unicode code points in the U+XXXX format: .. csv-table:: :header: "Code point", "Character", "Example" :delim: | U+002D | HYPEN-MINUS | \- U+0030 | DIGIT ZERO | 0 U+0031 | DIGIT ONE | 1 U+0032 | DIGIT TWO | 2 U+0033 | DIGIT THREE | 3 U+0034 | DIGIT FOUR | 4 U+0035 | DIGIT FIVE | 5 U+0036 | DIGIT SIX | 6 U+0037 | DIGIT SEVEN | 7 U+0038 | DIGIT EIGHT | 8 U+0039 | DIGIT NINE | 9 U+0061 | LATIN SMALL LETTER A | a U+0062 | LATIN SMALL LETTER B | b U+0063 | LATIN SMALL LETTER C | c U+0064 | LATIN SMALL LETTER D | d U+0065 | LATIN SMALL LETTER E | e U+0066 | LATIN SMALL LETTER F | f U+0067 | LATIN SMALL LETTER G | g U+0068 | LATIN SMALL LETTER H | h U+0069 | LATIN SMALL LETTER I | i U+006A | LATIN SMALL LETTER J | j U+006B | LATIN SMALL LETTER K | k U+006C | LATIN SMALL LETTER L | l U+006D | LATIN SMALL LETTER M | m U+006E | LATIN SMALL LETTER N | n U+006F | LATIN SMALL LETTER O | o U+0070 | LATIN SMALL LETTER P | p U+0071 | LATIN SMALL LETTER Q | q U+0072 | LATIN SMALL LETTER R | r U+0073 | LATIN SMALL LETTER S | s U+0074 | LATIN SMALL LETTER T | t U+0075 | LATIN SMALL LETTER U | u U+0076 | LATIN SMALL LETTER V | v U+0077 | LATIN SMALL LETTER W | w U+0078 | LATIN SMALL LETTER X | x U+0079 | LATIN SMALL LETTER Y | y U+007A | LATIN SMALL LETTER Z | z U+0101 | LATIN SMALL LETTER A WITH MACRON | ā U+0113 | LATIN SMALL LETTER E WITH MACRON | ē U+012B | LATIN SMALL LETTER I WITH MACRON | ī U+014D | LATIN SMALL LETTER O WITH MACRON | ō U+016B | LATIN SMALL LETTER U WITH MACRON | ū Terminology and standards ------------------------- The .nz IDN implementation must be compliant with the technical requirements described in various RFCs (3454, 3490, 3491, and 3492) collectively called the "IDN standards". There are a lot of terms and definitions in use related to IDNs mentioned in the RFCs and other IDN documents. Listed below are some brief definitions of the common terms. Refer to the RFCs for the comprehensive definitions. The external-form or display form of an IDN is called U-label and the internal-form or stored form is called A-label. The U-label string is the Native Script name in Unicode. This is normally the display format of the name and is how the user enters the name in a web browser. This name is also known as the IDNA-valid string. The A-label string is the ASCII-Compatible Encoding (ACE) form of the U-label. This name is also known as the "punycode" name. Every A-label will begin with the IDNA ACE prefix, "xn-\-" followed by a string that is a valid output of the Punycode algorithm and hence a maximum of 59 ASCII characters in length. The prefix and string together must conform to all requirements for a label that can be stored in the DNS including conformance to the rules for the preferred form described in RFC 1034, RFC 1035, and RFC 1123. A string meeting the above requirements is still not an A-label unless it can be decoded into a U-label. Conversions between U-labels and A-labels are performed according to the "Punycode"specification [RFC3492], adding or removing the ACE prefix as needed. .māori.nz 2LD and DNS --------------------- All names registered under .maori.nz are duplicated in the DNS and available under the 2LD IDN variant .māori.nz (.xn-\-mori-qsa.nz) The duplication is achieved using a DNAME in the .nz zone files. IDN support via EPP ------------------- To register an IDN via EPP you use the EPP XML example for creating an IDN name as provided in the Registrar guide on the page at :ref:`irsote` and in the help section of the portal. An example is included below for your convenience. .. code-block:: xml xn--domain-with-mcron-z5b.co.nz 24 945-h-0 945-h-0 945-h-0 xxxxxxxxxxxxxxxx Latn domain-with-mācron.co.nz
