Of the hosts that attempted to connect to me:
- Over 50% had 135/TCP open.
- Several had 22/TCP open, and everything else closed (returning RST).
- One had 80/TCP open, and everything else simply dropping packets.

That 135/TCP is open is certainly surprising - these were all hosts  
using the Windows-like single-host-on-6to4 addressing, ie.  
2002:V4V4:V4V4::V4V4:V4V4.
