The obtained MAC address is the number of people online in the current local area network! The gateway is not counted!

Nice! Got it!
I once thought about how to easily and quickly know the number of people online in the internal network, but there was no result. I saw it today!
However, my internal network IP is in the form of "192.168.0.*", and it can be used by changing only one character.

It seems like we need to open 255 batch processing windows, and for computers with weaker configurations, well,...

Sometimes using this P to check the number of online users is really a bit frustrating, as so many windows need to be opened. Then nbtscan appeared. The following P processing is very fast to check the number of online users. Locally tested, it only takes a few seconds. nbtscan needs to be downloaded separately

After running, opened n many windows, when opened to more than 30, afraid that the computer can't stand it and turned it off, there is room for improvement.

for /l %%i in (1 1 254) do start /min ping -n 1 192.168.1.%%i
arp -a|findstr /v "00-00-00-00-00-00">>1.txt
Why is there no result after I run it?

Try adding parentheses...
for /l %%i in (1 1 254) do (start /min ping -n 1 192.168.1.%%i
arp -a|findstr /v "00-00-00-00-00-00")>>1.txt
