It does sound like they're doing something at least odd, if not  
completely wrong.  I suspect it's probably related to the way they  
substitute  opcode 3 (nxdomain) with their own answers -- they're  
probably making absolutely certain that the host doesn't exist, or  
something.  What you describe seems excessive, though.
