IDN

idn
















IDN (Internationalized Domain Name) encoding and decoding are crucial for working with domain names that contain special characters, such as those in non-Latin alphabets. By encoding these names into Punycode, you can ensure compatibility with the Domain Name System (DNS). Conversely, decoding allows you to convert Punycode back into its original Unicode representation, making it human-readable.





This tool is indispensable for anyone working with multilingual domain names or ensuring DNS compatibility for international web applications.










Key Features:





    

  • Encode: Converts domain names with special characters into Punycode for DNS compatibility.
    • 




  • Decode: Converts Punycode back into human-readable Unicode.
    • 




  • Command Output: Provides Linux-based idn commands for encoding or decoding, ready to run directly from your terminal.
    • 




  • Interactive: The form dynamically updates as you input text, showing the corresponding idn command and the processed result.
    • 











Common IDN Encoding and Decoding Options:





    

  • --encode: Encodes a Unicode domain name into Punycode.
    • 




  • --decode: Decodes a Punycode domain name into Unicode.
    • 











Examples of IDN Commands:





Encoding Example:





    

  • Input: 
    münchen.de
    • 




  • Command:
    > idn --encode münchen.de
    • 




  • Output: 
    xn--mnchen-3ya.de
    • 











Additional Encoding Examples:
Input: münchen.de
Expected Output: xn--mnchen-3ya.de
Input: пример.рф
Expected Output: xn--e1afmkfd.xn--p1ai
Input: españa.com
Expected Output: xn--espaa-rta.com
Input: täst.de
Expected Output: xn--tst-qla.de
Input: 中国.中国
Expected Output: xn--fiqs8s.xn--fiqs8s





Decoding Example:





    

  • Input: 
    xn--mnchen-3ya.de
    • 




  • Command:
    > idn --decode xn--mnchen-3ya.de
    • 




  • Output:
    münchen.de
    • 






Additional Decoding Examples:
Input: xn--mnchen-3ya.de
Expected Output: münchen.de
Input: xn--e1afmkfd.xn--p1ai
Expected Output: пример.рф
Input: xn--espaa-rta.com
Expected Output: españa.com
Input: xn--tst-qla.de
Expected Output: täst.de
Input: xn--fiqs8s.xn--fiqs8s
Expected Output: 中国.中国










Result Output:





The result of the encoding or decoding process will be displayed in the output section, along with the corresponding idn command. This command can be run directly from the terminal for real-time operations or saved for future reference.





This tool simplifies working with internationalized domain names, making it easier to bridge the gap between human-readable names and DNS-compatible formats.
