DNS control

[Nicholas Yau]

hi folks :
I have a dns up in my redhat 8.0 linux box.

-running bind-9.2.1-9.
-manually assign IP

actually i provide the service for my LAN user.
in network 192.168.42.x subnet mask 255.255.255.0

what i wanted to do is,
Only user and IP listed in the /var/named/named.xxx
can do the query from their machine to my linux box then
only out to the internet.


So that user cannot simply assign their own ip from the range
192.168.42.x as they like without informing the administrator.


help me folks !

Thanks
