Moving from ipv4 to ipv6

I want to configure the ip address of a computer to ipv6. The OS is Windows XP. From what I know, to enable ipv6 in Windows XP, you only need to run the command “ipv6” in the command prompt. The command should be “ipv6 install”.
But still, that computer connects to an ipv4 network. What do I need to configure in that computer?

Thank you for your responds.
