(Internationalized Domain Name) A .com or .net domain name that is represented in non-English characters and symbols, with .com and .net appended at the end in English letters. IDN names are encoded in Unicode and display in their native language such as Chinese, Japanese or Korean. When entered into a Web browser or other application for name resolution by the DNS system, the Unicode is converted into ASCII Compatible Encoding (ACE), also known as "Punycode." The Punycode is an ASCII representation of the Unicode characters and symbols. See Unicode.
