Get local network ip addresses on NodeJS server

Question

I need to get the info.(private ip address and MAC) of who made a request to a nodeJS server. This is running on an intranet, so i suppose i could get the MAC data somehow, and the ip from os.networkinterfaces() or req.connection isnt useful to me since they give me the server or the public ip respectively.

Answer 1

local-devices

Npm

npm install local-devices

Example

// Using a transpiler
import find from 'local-devices'
// Without using a transpiler
const find = require('local-devices');
 
// Find all local network devices.
find().then(devices => {
  devices /*
  [
    { name: '?', ip: '192.168.0.10', mac: '...' },
    { name: '...', ip: '192.168.0.17', mac: '...' },
    { name: '...', ip: '192.168.0.21', mac: '...' },
    { name: '...', ip: '192.168.0.22', mac: '...' }
  ]
  */
