did something similar recently...
dhcpd.conf
--------------------------------------------------------------------------
class "VMware" { match if ( substring(hardware,1,3) = 00:50:56 ); }
subnet 10.1.1.224 netmask 255.255.255.240 {
#other subnet specific stuff here
pool { allow members of "VMware"; range 10.1.1.229 10.1.1.230; }
pool { deny members of "VMware"; range 10.1.1.236 10.1.1.237; }
}
