That depends on your wireless device. I use Linksys and use static

This might work for wireless, however in a mixed environment,
where one DHCP server is serving both wired as well as wireless,
that might not work. Assuming a client actually broadcasted a
DHCPREQUEST to get an IP, you can have the DHCP server deny it based
on it being an unknown MAC. But if someone manually configures
their machine and simply plugs into your network, how will your DHCP
server know to block them? It never assigned an IP to them, it
never even received a request for an IP, so how would it know what
to do?
Not sure but I know it's possible. I work at a very large university
that does exactly that. If your mac address is not properly
registered and it is sensed on the network, even if you manually
configure the ip address, your port will shut down. Is that
accomplished through switch management?
