I have used Advanced IP Scanner for several years. I have the latest version installed and have obtained reliable results until recently. My View tab settings only have show alive checked. When I perform a scan of my IP range, 192.168.20.x, all 254 possible connections now show as alive with content displaying for truly live connections. I have cleared my saved items, but most scans display in this manner. Every once and awhile, the scan will yield the results I have historically received, i.e. only actual "live" connections being listed. .
