Mmmh.  To clarify: this is not 

 "DENIC not responding to DNS queries (packets) from 6to4 addresses"

but this is 

  "DENIC refusing to delegate a new .de domain to nameservers that 
   have (only) 6to4 connectivity".

DENIC does DNS checks before delegating a zone.de, and their rules
are numerous and amazing...

But in *this* case, I'm not going to argue the case - the usefulness of
6to4 connectivity for a name server is something which you can spend
debating hours and hours, and people will still disagree :-)

It's policy, and it's not a technical issue.  So as a transport provider,
there is nothing we can do about it.
