As all CloudStack VM's MAC address starts with 06 so I configured the external DHCP not to allocate IP to VM but cloudstack DHCP still can allocate the IP to other physical machines in my network. So I want help on this, What can be done so that my cloudstack DHCP vm does not allocate IPs to other machines in network.
