Slight preference for the first format (less typing ;), but I'm a network
guy and not a systems guy.
You probably also
* want to be able to monitor a DHCP server that is not on the same subnet as
the sysmon server (DHCP relay)
* don't want to block an IP address from the pool just for monitoring, so
sysmon could release the IP just after it has obtained its lease
Maybe I'm asking too much? (I'd of course be honoured to assist you within
the limits of my little knowledge, if required.)
