Apparently, it's not fake (although I didn't scan the *whole* space). I
bet there's some trick there, though. -- I don't expect them to be
running 2**64 servers...

With a little bit more of research, it shouldn't be hard to check
whether the responses are legitimate or not (TCP timestamps, IP IDs,
etc. are usually your friends here).
