The books says, after IPv6 is enabled on Windows XP, auto configure will give it 3 addresses, a Link, a Public, and a Temporary one.

But on my computer, I could only see Link, what was the problem? I used the Windows XP machine. But when I try it on Windows 2007 it works fine and show me a public address.
