DNS doesn't work like that.
Stubs (like your SUN) query recursive name servers.
Recursive name servers (don't know about zones in advance) query
authoritative name servers (which hold the original copy of zone
Confusion arises because BIND performs both roles by default,
but if you mentally seperate the two roles (DJBDNS seperates
these roles into two seperate executables, often run on
different servers), then you'll see the problem is the recursive
resolvers you are asking don't know about the other zones.
This means the zones aren't delegated correctly. There are ways
of bypassing delegation (slaving all the zones, stub directives,
forwarding), but they all boil down to making sure both
recursive resolvers have the same view of the name space, which
is a good thing from a redundancy perspective as well.
