[Kea-users] group by mac addresses ?

Hi guys.

I had in my old dhcpd this, which I believed worked:

group {
   # VMware
   ignore client-updates;
   deny client-updates;
   ddns-domainname "vmware.mine";  # this is critical 
regardless of the rest, for DDNS
   option fqdn.no-client-update true;
   option fqdn.server-update true;
   option fqdn.fqdn  "vmware.mine";
   option domain-name  "vmware.mine";
   default-lease-time    86400;
   max-lease-time        86400;

   host hub.vcentre.vmware {
     hardware ethernet 02:98:1b:6d:36:12;
     fixed-address     10.3.1.230;
     option host-name "vcenter";
   }
   host vcenter.vmware {
     hardware ethernet 02:02:bf:56:c0:a0;
     fixed-address     10.1.1.230;
     option host-name "vcenter";
   }
   host hub.esx1.vmware {
     hardware ethernet 02:9d:f7:79:a7:17;
     fixed-address     10.3.1.231;
     option host-name "esx1";
   }
....
...
}

Simple idea there was to have a group of hosts qualified by 
their mac addresses, then such group would share some options.
I've not started using Kea yet and cannot figure out how 
such logic can be realized in Kea - would some experts mind 
shading some light on how this is done?
many thanks, L.
