Which command lets a tester enumerate alive systems in a class C network via ICMP using native Windows tools?

ping 192.168.2. is syntactically invalid - the ping command requires a complete IP address or hostname and will fail to execute.

ping 192.168.2.255 sends a single ICMP packet to the subnet broadcast address, which does not individually probe or enumerate each host in the range.

The syntax 'for %V in (1 1 255)' uses the file-set form of the FOR loop, not the /L counter form, so it would not iterate numerically from 1 to 255 as intended and would also include address .255 which is the broadcast address.

The 'for /L %V in (1 1 254) do' construct uses the Windows FOR loop with the /L (list) switch to iterate a counter from 1 to 254 in steps of 1, covering all valid host addresses in a /24 network. The '-n 1' flag limits each ping to a single ICMP echo request for speed, and piping through 'FIND /I "Reply"' filters output to show only hosts that responded, making it an effective ping sweep using only built-in Windows tools.
