Today DK Hostmaster has performed a number of service upgrades to support registration of .dk domain names containing the German character ẞ.

The following services have been updated:

  * EPP ( to version 3.5.1 – no changes to XSD
  * Self Service ( to version 4.26.2
  * Registrar Portal ( to version 2.7.0

More information regarding this new feature can be found here:

Please be aware that not all software follows the IDN standards from 2010, which means that ẞ is used correctly in, for example, your web browser. In software that does not follow the IDN standards, you may risk ẞ being “translated” to “ss”, which may mean that another website or web server will be displayed.
A list of known IDN-compliant software can be found here:
