@echo off & For /L %i in (1,1,255) do @ping -n 1 192.168.10.%%i | find “Request” >nul & if errorlevel 1 @echo 192.168.10.%i >> %USERPROFILE%\Desktop\ipaddresses.txt

I had %%i incorrectly before which should be %i. The %%i in the second one is correct since it is in a batch file.

Oh, and the arp -a command only gives you your computer’s IPs, which you can get with ipconfig /all as well.

There is also a program called “Advanced IP Scanner (v2.1.200)” which you can download free from radmin.com if you prefer a GUI. It shows IPs/NETBIOS names in your subnets and has some options.

Enjoy!

@echo off & For /L %%i in (1,1,255) do @ping -n 1 192.168.10.%%i | find “Request” >nul & if errorlevel 1 @echo 192.168.10.%%i >> %USERPROFILE%\Desktop\ipaddresses.txt

Alternately, you could put the above command in a bat or cmd file and test for any subnet on the command line. Open up notepad and save the following…

@echo off & For /L %%i in (%4,1,255) do @ping -n 1 %1.%2.%3.%%i | find “Request” >nul & if errorlevel 1 @echo %1.%2.%3.%%i >> %USERPROFILE%\Desktop\ipaddresses.txt

… into a file which you save as SUBSCAN.CMD or [your_filename].bat or whatever (using .bat or .cmd extension in WinXP & up), and save the file somewhere in your PATH folders (to find these use the PATH command on the command line — usually C:\WINDOWS and C:\WINDOWS\System32 are fine). Then type:

subscan 192 168 10 0

to run the batch file. Note that you are replacing all dots (“.”) with spaces
(” “).

Enjoy!

and I get an error that goes by so quick I can’t see it. Can someone please attempt this in a batch and resolve the issue. I actually have commands that find the IP address and gatewa and save them to variables, I pass that into this code (instead of the 192.168.10.%1) but I need to remove the last octect. (don’t know how to do that either.) I don’t need to pass it into a file, just display the used IPs and resolve the name ( -a)
Would someone please put that in a batch and test it? This is a server test utility to see if the DNS is working.
