254 Threads (whew!!!) Batch file to ping any subnet (already tested) - China DOS Union Forum

//Using the 192.168.1. subnet as an example
ipconfig /all >ipconfig.txt
find "Default Gateway" ipconfig.txt >IP.txt
for /f "skip=2 tokens=13" %%a in (ip.txt) do echo %%a >ip.txt //Shows as 192.168.1.1 (gateway)

for /l %%p in (1,1,254) do start %%p.bat //254-thread command splicing
ping 1.1.1.1 -n 2 //Used for delay (I could only think of a simple one)
arp -a >arp.txt //Shows online IPs and MACs on the subnet. In current XP, if you don't ping them first, arp -a is useless. Everyone can try it, it will only show the gateway info.
del ipconfig.txt ip.txt

Although it's not a very mature work, it's practical. How come nobody is discussing it or giving some pointers, sheesh!!!

The statements are too cumbersome, can any expert help revise it!!!

Your batch processing really does need a lot of simplification!! I suspect your batch file simply can't get the result you want!!! At most it only gets your own gateway!!

Take a look at mine

@ipconfig /all | find "Default Gateway" >c:\1.txt

@for /f "tokens=1,2 delims=:" %%a in (c:\1.txt) do set ip=%%b

@echo %ip%

@set i=%ip:~1,9%

:loop

@set /a a+=1

@start /i /min ping -n 2 -w 500 %i%%a% >nul

@if "%a%"=="20" exit

@goto :loop

RE 429499381:

Yours also only gets the gateway of the local subnet...

Hehe...

These are all not very mature works
You can refer to some earlier discussions

My batch statements are cumbersome, but the result is definitely all online IP information on the subnet where the operating machine is located! Everyone can test it first before commenting.
