How does os.networkInterfaces work?

The os.networkInterfaces() method is a built-in Node.js module that returns an object containing information about the network interfaces of the current machine, such as IP address, MAC address, and network prefix length, among others.

const os = require("os");

const interfaces = os.networkInterfaces();

Object.keys(interfaces).forEach((ifaceName) => {
  const iface = interfaces[ifaceName];
  console.log(`Interface ${ifaceName}:`);
  iface.forEach((addrInfo) => {
    console.log(` ${addrInfo.family} ${addrInfo.address}`);
  });
});

This code retrieves all the network interfaces available on the system and prints information about each one, including its name and the IP address assigned to it.
