DNS quieries for "teredo.ipv6.microsoft.com"

[Mike]

I work off of a shared 56K internet connection in our
small office and recently noticed many entries per day
for my PC for DNS quieries to the subject server. I know
in general what IPV6 is, but certainly have no need of it
at present. How do I stop my PC from sending out these
DNS queiries so I can preserve bandwidth for the staff
and myself?

TIA,
Mike
