As a Linux enthusiast, I enjoy tales of Microsoft doing something
ignorant. And truly, what could be more foolish than arranging for
your flagship product to automatically reroute packets through
low-bandwidth volunteer-run 6to4 gateways?

Sadly, I must report the story to be false. My Windows 7 laptop did
not, in fact, install a 6to4 adapter or configure an IPv6 address when
I reprogrammed my DHCP server to give out a global scope IPv4 address.
And the Teredo Tunneling interface remained in state "Media
disconnected." Indeed, only the normal fe80 link local IPv6 address
configured itself on my machine.

You are mistaken sir.
