I would like to be able to scan individual IPs that have been input using a CSV.
I agree. I had limited success scanning approx 10 x /16 subnets for devices in a retail environment (2-3 devices per store).
Would be great to either upload a CSV file with IP/Serial/Hostname, then get Active Advisor to actively scan the devices using the client or web app, or better yet, to allow you to control the host portion / last octet of the scan ranges (eg, scan 10.*.*.250-254), or use a wildcard like: 10.(1-9).(0-255).(250-254).
