Objectif (Brief): Le but de ce projet est de résoudre un bon nombre des questions fondamentales à la délégation des variantes TLD. Le premier projet concernant les questions relatives aux variantes des IDN a exploré les questions liées à l'inclusion éventuelle de variantes IDN TLD dans la zone racine du DNS, sur demande du conseil d'administration de l'ICANN et de la communauté. Les deux premières phases du projet ont été achevées avec la publication du rapport final des questions intégrées le 20 février 2012 et le projet se trouve maintenant dans sa phase suivante. L'ICANN a créé un plan de programme pour les prochaines étapes, l'a affiché pour commentaires du public et l'a présenté lors d'une session de la réunion de l'ICANN au Costa Rica en mars 2012.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
