Do you mean the Internet Protocol version 6 or TCP/IP v6?
You will find this setting in Network Properties by right clicking the network connection you are using and selecting properties in the network and sharing centre from the control panel in vista!
Start / Control Panel / Network and sharing centre / Manage Network Connections / right click the local or wireless connection your using / properties.
Should see it listed about 5 down from the top.....Check the box to activate it!
Basically, its the new version of Internet Layer protocol for packet switched Inter networks
and the Internet.
