This @MAC can be only used by this @IP

Hi all:

I have an wireless Access Point connected to a Openbsd box. Clients use
DHCP server to setup their IP addresses.

I want to ensure that every @MAC has always the same IP address. I can
configure DHCP server to achieve that, but users would be able to hardcode
their IP address with a valid @IP without using DHCP and therefore they
will use network resources with a another that they must use.

How can ensure that users always use the correct IP?

Thanks.
