Hi there.
So You are trying to find all the “active” devices / hosts in Your lan and the only thing You have accessible is a MS Windows command line?
Well…
Click on Menu Start > Run (or press [Windows_key] + [R] combo on Your keyboard. Type in:
cmd
and press [Enter].
IF You have set up the IP statically and / or You know the IP range of the network You are using You can skip this step.
Type in:
ipconfig
and press [Enter]. From here You will find out what IP has been assigned to Your machine by DHCP…
So lets say Your IP is 192.168.0.10. This means that _PROBABLY_ the rest of the devices in Your network will have 192.168.0.xxx IP addresses.
Knowing this use this command:
for /L %I in (1,1,254) DO ping -w 30 -n 1 192.168.0.%I | find "Reply"
IF Your IP range looks like 192.168.1.xxx
for /L %I in (1,1,254) DO ping -w 30 -n 1 192.168.1.%I | find "Reply"
and so on…
Unless the devices are set to drop ICMP requests You should be able to see ping replies from the active hosts.
Cheers.
