Yep, and you're only seeing native data there.

Do you have any bead on how much of the IPv4 data is protocol 41 (I.e.  
IPv6 tunnelled over IPv4)?

I'm not going to ask you to find out how much of it is Teredo - that  
requires stateful DPI - but I expect it to be a non-insignificant  
number.


Those numbers can't be added together, because depending on a couple  
of factors (ie public relays and things), tunnelled traffic could be  
counted twice - once when encapsulated, once when native.
