ipv6 dns query on MacOS X 10.3

[pui ming Wong]

I have set up a ipv6 dns server.
Now want to use the Mac client to see if
DNS queries could be obtained from the server.
In ipv4, normally the dns server have to be 
given manually (or via the dhcp/bootp server)
But on Mac , the ipv6 config is automatic.
Does it mean it will know automagically which ipv6 dns server
is out on the same network to help the name queries?
In other words, there is no way (like in ipv4) that i  could
specify the dns server for this Apple ?
