In actuality it takes about 500ms per iteration. I hear Windows has some kind of rate limits on ping, so maybe that's it. Not sure why my 150ms timeout isn't respected as far as speed of execution of the ping command. My batch script just does a pipe to FIND looking for "Reply" and so only prints the Reply lines of hosts that don't time out: ping -n 1 -w 150 192.168.%%i.%%z | FIND /i "Reply" No idea why both scanners are telling me these hosts are alive. Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), If I just use ping from cmd without any parameters, I get exactly what you'd expect from a non-existent host (actual copy and paste from cmd window, down to the hanging comma): ping 192.168.168.15 Maybe there is a fix for this or an alternative IP scanner that works well on Windows? I'd really just like AngryIP scanner to work again and stop telling me timed out hosts are alive and to still function if my laptop wakes from sleep. I got so fed up with it that I currently use a batch file instead, but even that takes a really long time (121 seconds for the same IP range), even with the -w option set to 100ms. Finally, if my computer ever goes to sleep, AngryIP Scanner stops working (starting a scan just sits there doing nothing) until I reboot. Additionally, no matter what value I put for the ping timeout, it always seems to wait quite a long time, making scanning 250 ip addresses with 250 threads take over 17 seconds. For the past while now, AngryIP scanner has been erroniously reporting all hosts alive, even though they clearly timed out and do not exist. I have Windows 10, probably will be on 11 in the near future and I often need to scan IP ranges to find living hosts. u/RoweDent created this awesome resource on network theory u/tht1kidd_ has created a suggestion post regarding information everyone needs to provide when asking a question about their network There have been some excellent guides written in this sub, and we're always looking for more!

Despite the name, you don’t need to be angry to use it, and the calm, green interface certainly works the opposite way. Naturally, it also serves as an information-gathering tool for several purposes. Unique in the truest senseĪngry IP Scanner is one of the few apps for Android that allow this kind of operation, which is good news for anyone in need of quickly assessing networking issues. If you want to add more information about an IP, click the Tools menu, and choose Fetchersv. Step 3: By default, the software only displays Ping, Hostname, and Ports. Step 2: Pull down the menu next to IP Range, and choose the desired mode. This is incredibly useful when you need to troubleshoot network issues or gather info but have no computer at hand. Run Angry IP Scanner after downloading for free. Then you can select one to view more information, such as opened ports. Just select an IP range and ports, and it’ll display information about connected devices, including whether they’re dead or alive. Straightforward interfaceĪngry IP Scanner is very simple to use. And it isn’t currently possible to save results to different file formats like CSV, TXT and others. Angry IP for Android conserves many of those features, but given the nature of phones, it lacks others, such as displaying NetBIOS information.
