Domain name Holder´s FAQ

  • General information
  • Registering a domain name
  • The migration of domain names registered with DNS-LU to the online platform my.lu
  • IDN domain names
    • What are domain names starting with 'xn--'
    • What encoding is used

      For .lu IDN domain names are encoded according to IDNA2003.

      The more recent revision IDNA2008 is not supported. The local character that is thus not available is 'ß' used in german.

      More details can be found at unicode.org.
