Re: Bind cache availability...

 I'm running Woody distribution of Debian Linux on one of my servers and
I use it as DNS sever - bind installed on it...
The DNS server is available to LAN users as same as to internet users...
For nonexistent records I use hint zone instead of forwarding to my
provider...this means, I use cacheing of records from root servers...and
that's the problem...records in my cache are available to internet and
LAN users, which I don't want for security reasons...I would like them
to be available only to my LAN users. Is it at least possible...?

Yes.  Set up an acl containing your IP blocks, then set up two separate "view" 
groups and use "match-clients" to filter down the list of IP's that are 
matched into each view.  For the external clients, set "recursion no."
