client took a host assigned ip

[anthony]

v 3.0.4

I have a mac os client that for some reason requested an ip that was not 
in dhcp range but rather was a host assigned ip.

The logs show the dhcp server never offered the ip to that mac os.

How do I ensure not no clients get host assigned ip's.

Do I need to   make a pool of host assigned ip's and deny the clients 
like this?


        pool {
                 failover peer "dhcp-failover";
                 range 10.15.49.101 10.15.49.119;
                 range 10.15.49.130 10.15.49.254;
                 option domain-name-servers 10.15.61.5;
                 deny dynamic bootp clients;

         }
         pool {
                 range 10.15.49.33 10.15.49.35;
                 deny all clients;
         }
