Working Webhosting for .DE domains?

Hi,

I already have three different hosting services, but none of them can be used with a .de domain. The .de domains got some special regulations like two different C class IPs in the namerservers or something like this.

Which hosting are you guys working to use .de domains? Few years ago I used Bluehost and I think (not sure) they were working on there. If so, does it still work on Bluehost?
