IPv6 DNS server addresses on WinXP

I have a bit of a query about IPv6 on WinXP, ipconfig /all shows the
following for DNS servers, but does not appear to work, I know the
addresses are depreciated, however, if the above commands show them,
they should at least be used right?

DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1

I have made sure that anything entering the work network to those
addresses gets forwards to a few DNS servers and have confirmed that
they respond on IPv6:

# dig www.google.com.au @fec0:0:0:ffff::1

; <<>> DiG 9.5.1-P1 <<>> www.google.com.au @fec0:0:0:ffff::1
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58797
;; flags: qr rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 7, ADDITIONAL: 7

;www.google.com.au.             IN      A

www.google.com.au.      27280   IN      CNAME   www.google.com.


To show this I have a secondary config for IPv4 address config on my
laptop, if it doesn't get a DHCP lease over wireless after a few minutes
it configures itself (don't have DHCP at home, but do on other networks
connect to and changing it all the time is not fun).

During the couple of minutes its waiting for DHCPv4 it has a IPv6
address via RA but I am unable to ping www.arrnet.edu.au or any other
DNS address (should at least get an IP, doesn't matter queries are over
IPv6, should get any address available).

Am I missing something or are those DNS servers reported just eye candy?
