Yeah, the DNS auto-discovery prolly has to do with it. Which is a draft
to solve the "we use just RA, but where do we get our DNS servers from".
(I am still in favor of a well known prefix for a 'local dns cache')
Prolly Vista/Win7 then, as the XP + 2000 + NT4 stacks never supported
DNS over IPv6 transport.
Effectively you should never ever see fec0::/10 as that was once
site-local and has been deprecated, site-local was never intended to be
routed (one of those reasons for only routing 2000::/3 on some boxes).
