I work on networks behind other people and have to find what IP's are in use. I have been using the IP Scanner to do this. The only problem I have found is that the program seems to keep a history file. Most of the time I do not care what use to be on the network only what is currently active. Example: say yesterday I scanned a network and found unit 192.168.1.4 as it was active at the time. If I scan it today it will still show the .4 machine even if it's been turned off. Is there a way to clear the history? Or to have the scanner not show inactive devices?
You need to delete stored data. You can find this option in the following way: Advanced IP Scanner -> Settings -> Options -> Misc -> Delete stored data.
