Bind cache availability...

	Hello list...

	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...?
Thank you in advance...
