DCHP Scope Options

If your only dealing with a couple of machines, just do reservations for them. It should make life a little easier.

There are no DHCP scope options that allow you to filter which computers are allowed to receive a DHCP supplied IP addresses based on MAC address (or any other parameter).

The "043 Vendor Specific Info" option is not used as a filter. It is used to distribute Vendor specific information. The types of information that can be distributed is defined by the vendor of the specific DHCP implementation. See paragraph 8.4 at the following URL:

Theonly way to do what you are attempting would be to create a DHCP reservation (which is tied to a specific MAC address) within the appropriate scope, for each client computer. You would essentially be applying fixed IP addresses while receiving the benefits of DHCP supplied DNS information.

Hope this helps.
