	IPv6 in Windows XP does not require command line activation since SP1.
You can turn it on by right clicking on the network connection and
adding the protocol.  You don't even have to reboot.

	What is, err, disturbing is that a significant number of XP systems
have ended up with IPv6 enabled and yet nobody knows how it happened.
That a globally addressable and routable protocol "magically appears" on
a box without the user having done it is very disturbing from a security
standpoint.  Some users have thought that it was due to a Microsoft
update, but we know that to NOT be the case.  This has happened even on
some embedded systems, such as POS terminals.

	Yes, when enabled, it does have Teredo enabled and is perfectly capable
of configuring itself to the MS Teredo servers and start chatting on
IPv6.  This has been occurring enough to be showing up on intrusion
detection systems with Teredo and 6to4 signatures enabled.
