The
Domain Name System, which performs a lookup service to translate user-friendly names into network addresses for locating Internet resources, is restricted to the use of ASCII characters, a technical limitation that initially set the standard for acceptable domain names. The internationalization of domain names is a technical solution to translate names written in language-native ......s into an ASCII .... representation that is compatible with the Domain Name System. Internationalized domain names can only be used with applications that are specifically designed for such use, and they require no changes in the infrastructure of the Internet.
