is no way to go back and work it out. You'll need to look at your dhcpd.conf and try to work out which pool matches the criterion. As far as detemrining the number of free leases you'll need to scan through dhcpd.leases and count them. THere are quite a few tools out there to do this, one I've used is dhcpstatus, http://dhcpstatus.sourceforge.net/ but there are many others. regards, -glenn
