IDNs are specialized labels displayed in a software application in a non-Latin alphabet or language-specific script. IDNs are stored in the [[DNS]] as ASCII strings. The DNS performs look-up services to ensure the translation of user-friendly names to locate the Internet resources, and it is restricted to using [[ASCII]] characters for acceptable domains. The "nameprep" protocol ensures the names written by means of non-ASCII scripts are translated into ASCII text compatible with the [[DNS]].<ref>This translation process is described in part by [https://www.rfc-editor.org/rfc/rfc3491.txt RFC 3491]</ref>

The syntax designed for the use of the IDN is known as "[[Punycode]]."<ref>[See [https://www.rfc-editor.org/rfc/rfc3492.txt RFC 3492] for a technical discussion of Punycode. The non-ASCII characters are transformed into a specific format containing only ASCII characters and then a unique identification is processed for the domain name. <ref>[http://www.quackit.com/domain-names/internationalized_domain_names.cfm Registering IDNs]</ref>
