I do a project that I using a computer as a local server, and my nodemcu 1.0 (esp8266 12e module) communicates with it by connecting to hotspot of my computer.
the ip of the computer changes every time i turn off the hotspot of the computer. the nodemcu is the only device that connects to the hotspot. is the esp8266 can scan all the ip addresses of all the devices that in the network of the hotspot (which is just the computer and the esp8266)?

thanks(:
