I have fully populated several subnets by importing them from tab delimited format files into the ip address details.
I have created the proper files for scanning with the ipplan-poller.php tool.
All works well with scanning but when I look at the subnet summary I see the subnet is 100% in use but the poller only reported 100 active IP address out of 254 and that is accurate if I were to scan myself and count manually.
On the IP addresses that do not respond I do have IP address details noted on them like hostname, description, and user notes but I know those Ip addresses are free but still reported as being used.
Why does this happen and what can I do to correct the reporting?
