This is mainly a sanity check.
I'm not experienced with BIND or DNS servers at all, however I'm wanting
to do the following, and would appreciate being told if it's a foolish plan.
My situation is the following: Internal net 10.0.0.0/24. I have 8 static
IPs from my ISP (who takes care of rDNS, my domain host takes care of
forward lookups. The static IPs are 217.x.x.168/29.
I have pf doing binat from static IP to internal IP for several boxes on
What I'd like to do is set up BIND (or any nameserver) such that clients
on the internal network resolve the hostnames of the binat'ed (and all
internal) boxen to their internal IPs rather than the 217.x.x.x, and to
cache(?) dns lookups for the wider internet. I do not want to serve any
DNS for anything outside 10.0.0.0/24.
Is this 'split-horizon' dns? Is
a good place to be looking? If not, what sort of path should I take?
