Open a cmd.exe session and enter the following.

for /l %i in (1,1,254) do ping –w 100 –n 1 10.0.0.%i | findstr “Reply”

Where 10.0.0. is replaced with your subnet address e.g. 192.168.20.

Adjust the range of hosts you want to scan by change the first 1 in brackets and the final value. For example if you only wanted to scan from host 20 to 50 you would make the values in brackets (20,1, 50)

for /L %i in (1,1,50) do @ping -w 100 -n 1 192.168.80.%i | findstr “Reply”
