Internationalized Domain Names - IDNs
Since March 2004, DENIC has also been offering Internationalized Domain Names (IDNs). The new standard enables a total of 93 additional characters, including umlauts, to be used in .de domains. For further details, also with regard to the technical background of IDNs, please refer to our FAQs, where we provide such information in the form of questions and answers. Furthermore, we would like to draw your attention to our comments on alleged security problems with IDNs. Please note that some older program versions of browsers or e-mail software may not support IDNs. Our conversion routine allows you to see how an IDN is technically implemented by showing you the so-called ACE string.
