dhcp whitelist
 

Hello,
I'm looking for a way to setup a DHCP Whitelist so that my
ISC DHCPd version 3 server does not hand out IP addresses to clients not on the Whitelist. Is this possible?
Configuring a DHCP reservation for each authorized client is not an
option.
I'd simply like to be able to feed my DHCP server a Whitelist of MAC
addresses and tell it to not hand out a DHCP address to any clients not
appearing on the Whitelist.

Thanks.

Did you do any research before asking a question. Here's my 5 seconds worth of research. Man dhclient says in part:

~~~~~~~~~~~~~
It is also possible to specify interfaces by name in the dhclient.conf(5) file. If interfaces are specified in this way, then the client will only configure interfaces that are either specified in the configuration file or on the command line, and will ignore all other interfaces.
~~~~~~~~~~~~~~~

Is that what you want?
