DNS and Ipv6

I'm testing an IPv6 environment.
Server1: IPv4 and IPv6, DNS and DHCP.
Configured to listen for DNS on IPv6 -> dnscmd /config
/enableipv6 1
Added the IPv6 addresses -> netsh interface ipv6 add address
"Local Area Connection" [IPv6 address as below]
FEC0:0:0:FFFF::1
FEC0:0:0:FFFF::2
FEC0:0:0:FFFF::3
Server2: IPv4 and IPv6, IIS, DNS server Ipv6 addresses set to Server1
Server3: IPv4 and IPv6, IIS, DNS server Ipv6 addresses set to Server1

With both IPv4 andIPv6 installed on all servers, I can ping and resolve Ipv4
and IPv6 addresses.
I'm trying to set up a pure IPv6 environment. It seems I must have IPv4
protocol enabled on Server1 or DNS service doesn't start. Once I remove IPv4
on Server2 or Server3, I can no longer resolve names using DNS. Network
analyzer Ethereal does not show any connection using the IPv6 protocol for
DNS. I can ping the DNS server using the IPv6 address from Server2 and
Server3. I can telnet to the DNS server using the IPv6 address and port 53
from Server2 and Server3.
Is it possible to have all three servers using only IPv6? Am I missing some
configuration settings for DNS using IPv6?

I'm not completely sure about this, but I believe that Windows 2003
only
supports using IPv4 and IPv6 together. It is a "dual-stack" instead of
two separate stacks.I know that the DNS server will support both v4
and
v6. However, I could only get it to work if you configure non-site
local
addresses for each network.

Google: `` "Exploring IPv6" site:microsoft.com '' for the TechNet
article on IPv6 support.

It's a shame because I was really looking forward to a pure v6 network
in my current project. What finally put the nail in the coffin so to
speak was the lack of v6 support in the DHCP server. Maybe I'll
revisit
things once we adopt 2008. Oh well...
