Would you please consider adding functionality to enable WHOIS queries to German DE domains?
The root of the problems seems to be that DENIC (the German domain registry) does not implement ICANN's specifications but requires that WHOIS requests conform to their own ones.
Their (English language) description can be found here:
https://www.denic.de/en/service/whois-service/
It is very short, so I'll quote it:
"To query the technical data and the date of the last change to the domain data please use "whois -h whois.denic.de -T dn <domain.de>"
Shouldn't be too difficult to implement from the technical side.
Please help that Windows users can request at least some information about German internet domains.
Have a nice day
