How would you approach this task, without an Arduino? That is, how would you use your PC to get the same information?

The only approach I can think of would be to iterate over the last two octets in the IP address range (192.68.n.m) where n ranges from 0 to 255 and m ranges from 0 to 255, trying to ping the device. If you get a response, that IP address is part of the LAN at the time the scan was done. If you don't get a response, then the IP address is currently not in use.

Yes
I want to use Arduino, and if possible with esp32 or esp8266.
Thank you for replay

Figure out how to accomplish the goal with a PC first. Then, implement the solution on the ESP.
