DNS: configure bind9 to resolve only a certain IP-range

[Hans Wilmer]

Hi,

how can I configure bind9 so that it would (reverse-)resolve a certain 
range of IP-addresses only within a zone?

We�ve got a consecutive range of IPs for our permanent internet-connection 
(a.b.c.64 to a.b.c.71), and I want our nameserver to resolve those 
addresses from its local zone files while still being able to 
(reverse-)resolve all addresses outside of our own range. For example, a

  �dig -x a.b.c.1�

should give appropriate results, and

  �dig -x a.b.c.65�

should work also, giving as result what I�ve configured.

I�ve been browsing through some documentations, but I couldn�t find any 
option or something like that to tell bind that it is responsible for a 
designated range of addresses only. Is this even possible?

Eventually, I could circumvent the problem by specifying a zone file for 
each address that is in our range, but that would be a very ugly solution.

However, this must be kind of a common problem; but how is it solved?

PS: You can query the nameserver in question @193.158.67.67.
