Ahh, try this :

subnet 10.11.12.0 netmask 255.255.255.0
{
    option routers 10.11.12.1;
    option broadcast-address 10.11.12.255;
    option subnet-mask 255.255.255.0;
    pool {
      range 10.11.12.2 10.11.12.254 ;
      ignore booting ;
    }
}

The unknown leases messages will be because the server isn't 
configured to offer that address. By adding a range statement in a 
pool, all the addresses will now be available for lease and hence not 
unknown leases. The "ignore booting" will avoid them being handed out 
to clients.
