Excuse my ignorance on this subject, been looking for
a link that explains the policy and why?  Right now I
have primary and secondary name servers hosting many
domains and web server applications that need to
resolve DNS from these servers.  Then I have a handful
of workstations that use these servers for regular DNS
queries.

This will be significant work/expense and to find
space for it just to separate the caching name server
to a separate box just so the stations can have DNS
queries.

Been doing it this way for years without a problem, so
any info you can pass on.
