I read this from Running IPv6:

C:\>netsh
netsh>interface ipv6
netsh interface ipv6>show addres
Querying active state...
Interface 6: Local Area Connection 3
Addr Type  DAD State  Valid Life   Pref. Life   Address
---------  ---------- ------------ ------------ -----------------------------
Temporary  Preferred   6d23h38m55s     23h36m8s     2001:db8:1dde:1:6d16:9d1:b1ec:2245
Public     Preferred  29d23h59m30s  6d23h59m30s 2001:db8:1dde:1:201:2ff:fe29:23b6
Link       Preferred      infinite     infinite fe80::201:2ff:fe29:23b6

The books says, after IPv6 is enabled on 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 tried running the same command in Windows 7 and I only got Public + a lot of Other – alex Nov 3 '09 at 9:47
    
I only got a "Link", ipv6 is quite complicated than I thought. – lilyonwind Nov 3 '09 at 10:33

You do not have a DHCPv6 server available so you are only getting a link local address by default. The auto-configuration process for IPv6 requires these link local addresses at a minimum, the other addresses are added as later steps in the auto-configuration process complete.

See http://www.tcpipguide.com/free/t_IPv6AutoconfigurationandRenumbering.htm for a description of the process.
