What is IDN (Internationalized Domain Name)?

IDN was initially proposed in December 1996 by Martin Durst and executed in 1998 under the direction of Tan Tin Wee by Tan Juay Kwang and Leong Kok Yong. An internationalized domain name (IDN) contains at least one label that is shown in programming applications, in a language-specific script or alphabet, like Chinese, Cyrillic, Devanagari, the Latin alphabet-based characters with diacritics. Internationalized domain names are stored in the Domain Name System (DNS) as ASCII strings using Punycode transcription.
