After successful conclusion of the test phase, the thoroughly revised DENIC information service public-whois was made available in the production environment on 21 September 2010. It replaced the former whois server. The address of the whois has remained unchanged. To access it go to whois.denic.de.
The consolidation measures did not only include a new architecture of the whois but also optimization of its functions:
Systematic elimination of inconsistencies and simultaneous standardization of the parameter and output syntax make the new whois much more user-friendly.

A special information page will give you a first idea of the amendments and innovations. You can call it at http://www.denic.de/en/background/whois-service/changes-within-public-whois.html. Here, you will also find the new public-whois documentation with detailed explanations of all important items.
