Why in the world would the software giant enable an IPv6 feature at this point in time by default? Who in Redmond is smoking what??? I am certain that mr and mrs joe america are hopping right on the IPv6 over IPv4 train as it comes down the track. the same people who cannot get wireless to work are now the tech gurus of the day, using the bright shiny new protocol. Come on Microsoft, the issue is not Potato security....oops Teredo security, it is applicability. No wonder Vista runs so slow.
