On killing IPv6 transition mechanisms

I have a number of them here (the 6to4 is being provided by FreeBSD, not
an airport, but all the clients are OSX). What would you like me to test ?

BTW, I belive there is some kind of issue with how OSX resolves names
with bot an A and an AAAA record. I have a feeling that it makes two
requests, but only uses the one which comes back first or something
along those lines... Certainly I use Ipv6 on OSx all the time for my
work, and one of the annoyances is that an IPv6-only website which was
previously accessible can suddenly vanish as far as Safari is
concered. Quitting the app and disabling-the-reenabling wifi makes it
appear again.
