The intention certainly wasn't to scare anyone -- for instance, I didn't
expect these results ot be that bad.

The goal of this measurements was to get some data regarding on where
we're standing with respect to IPv6 fragmentation and extension headers.

This is just data that is useful and should keep in mind when developing
protocols and/or extensions.

Thanks,
