Question

Node.js

Hello!! In short, I'm making a local game on nw.js. And in order to connect to another computer in the program, you need the Host's ip! The question is this!!!
How can I get all ip addresses on a local network?
I will be glad to everyone who will answer☆☆
And I apologize for the mistakes, I'm not Russian!

Answer 1

The wrong way is to take an address and a netmask (from which you can easily calculate all possible addresses) and scan the network, finding working computers.
Correct - one host should send a broadcast to the local network at a certain interval, and the other should listen and show the found game.
Simple - get a local address on the second computer and display it to the user, the user will simply tell it to another player and he will enter it manually.
