Anyone have an answer for this?
Sorry for the delayed response. The machines are gone but are the reservations still active in your DHCP server? If there is an active reservation, then the address is not available, hence it is used.
I see what you are saying. However, I would like for it actually show me the REAL "last response time", not just what is listed in DHCP.
That leads me to my next question I guess.
When monitoring a DHCP scope. Does IPAM try to ping the ip addresses, or does it just report what is in DHCP?
If that's the case, I guess I could create a subnet with the same IP address range. Since IPAM does attempt to ping all addresses in a non "discovered" subnet.
Kinda defeats part of the purpose of managing DHCP servers though.
