node module for iterating virtual network interfaces

forEachInet

Invokes a callback for each network interface socket address object, since the return value of require('os').networkInterfaces() is weird to iterate through.

Installation

npm i foreachinet

Example

var forEachInet = require('foreachinet');

forEachInet(function (inet) {
  console.log(inet);
});

prints:

{ address: '::1',
  netmask: 'ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff',
  family: 'IPv6',
  mac: '00:00:00:00:00:00',
  scopeid: 0,
  internal: true }

as opposed to:

console.log(require('os').networkInterfaces())

which prints:
