Split DNS with BIND 8 with one server?

[dbotham at edeltacom.com]

I think what is being suggest is that you run two instances (servers) of
bind on the same physical systems.  Have one instance listen on an external
addresss and serve external dns and have the other listen on the internal
address and serve internal dns.  If you have turned off IP forwarding on
the system (recommended) have the internal instance "forward" to the ip of
the external instance.  This forwarding will allow internal resolvers
(using internal instance) the ability to resolve externally...

That is to say:

>            Use two servers bound to different addresses.
Means two instances of the BIND server software  bound (listening on)
different [IP] addresses...

Okay.  In the interim, prior to upgrading to BIND 9.2.1, if one dispenses
with
a split-DNS configuration and uses only one DNS server which provides name
resolution for both external, routable hosts as well as internal,
non-routable
hosts (i.e. in the 10.x.y.z range), is this a breach of protocol?  Will
doing
this cause grief for external denizens of the Internet (who shouldn't be
trying
to access hostnames in that domain with internal non-routable IPs anyway)?
