I do not understand what point you're making. Or if there even is a 
point. DNS lookups provide a means of finding an end-point for some 
method of communication. This is completely orthogonal to how or even 
if that form of communication is used. Besides, getting the IP 
addresses of whatever looked up this intercepted number is a completely 
different thing from identifying the client which initiated the lookup. 
There's almost always at least one open recursive name server in 
between the originating client and the authoritative name server.
