IDN(Internationalized Domain Name,國際化域名)

IDN係透過Unicode標準編碼,使世界各地的人可以根據IDN相關協定使用當地的語言及文字(scripts)構成的域名,如https://中文.台灣http://おはよう.tw 等。ICANN所制定的IDN推廣計畫,主要著重於IDN ccTLD與gTLD的規劃及實施,亦對社群指導在域名系統第二層有效使用IDN的專案提供支援。

Internationalized Domain Names (IDNs) enable people around the world to use domain names in local languages and scripts. IDNs are formed using characters from different scripts, such as Arabic, Chinese, Cyrillic or Devanagari. These are encoded by the Unicode standard and used as allowed by relevant IDN protocols.

ICANN has instituted the IDN Program to assist in the development and promotion of a multilingual Internet using IDNs. The program is primarily focused on the planning and implementation of IDN top-level domains (TLDs), including IDN country code TLDs and generic TLDs. The IDN Program also supports projects geared towards effective use of IDNs at the second-level of the Domain Name System, as guided by the community.
