Pulled this down today to look for an IP I didn't recognize (found it easily by the way).
First time it scanned, it only took a few seconds and showed only the assigned IPs.
Went into settings, ticked a few options and on rescan, it took much longer and pulled and displayed every IP in the range (.0 to .254), most of which are empty. I though it was the Display Dead Devices, but apparently not. I want to see anything/everything with an IP assigned with as much information as possible about each one, but not the rest.
Rather than start all over removing them one at a time and rescanning, which might be doing it?
