Have you been a fan of IPScan32? Then you'll love Dipiscan! Why am I so sure of that? My answer in a few points: - its ergonomics, very close to that of IPScan32 so that you are not too disturbed, - its look, slightly modernized, - its features, enriched by the integration of those of WakeOnLan and the ability to modify / delete / add columns of information - its operation which no longer relies on DOS commands (PING, NBTSTAT, ARP, NSLOOKUP) whose use could cause problems on "localized" versions of Windows (translated into a language other than English or French) English), - its parameterization, allowing to more precisely configure the analyzes, - ts command line mode (DipiscanBatch.exe), for those who need to automate scan analysis, - its use in "portable" mode, thus the absence of installer, - but especially: its speed, because Dipiscan is not an evolution of IPScan32: it is a new tool totally re-thought and re-written in a language of modern development. No more VB5, now C# and multi-threading are in the place! Result: when the analysis of a strand previously required between 3 minutes and 5 minutes, sometimes even more, it is now completed in 10 to 20 seconds! And this by going back as much information as before, if not more. »
