Internationalizing Domain Names in Applications (IDNA) refers to a framework for handling domain names that contain non-ASCII characters, allowing for the use of language-specific scripts or alphabets. This system enables the global internet community to use domain names in local languages and scripts, effectively expanding the accessibility of the internet beyond the limitations of the ASCII character set. IDNA achieves this by translating domain names written in a user’s native language into a compatible ASCII format, known as Punycode, which can be understood and processed by the Domain Name System (DNS) infrastructure already in place. This process ensures that users worldwide can navigate the internet using domain names that reflect their language and script, promoting a more inclusive and diverse online environment.
