IDN stands for Internationalized Domain Name. An internationalized domain name (IDN) is an internet domain name that contains at least one character that is displayed in software applications such as web browsers, in whole or in part, in a language-specific script or alphabet, such as Chinese, Russian or the Latin-based languages with diacritics, such as German. An example would be Jörn.tel or 李.tel. These names will be seen in software applications such as web browsers. IDN-aware applications translate these names into traditional ASCII-only strings such as, for example, xn--1lq90i.tel. As a result, IDNs are displayed in their internationalized form in the user interface, while internally applications and servers communicate using ASCII-only forms of the same domains. Every registered IDN must be associated with a specific language.
