At first glance, it might sound like the security engineer is being a big 
meanie.
  But in fact many college networks still use older equipment which may not 
properly handle IPv6, and so blocking it is about all they (we!) can do.

  There's no good reason that merely blocking that protocol should kick 
people completely off the network, or interfere with access to the vast 
majority of the Internet -- either the security engineer is being a little 
over-zealous, or perhaps Vista doesn't work right when the local network 
doesn't support IPv6.
