Description

@gireeshpunathil
  • Version: v9.0.0-pre (not a regression though)
  • Platform: AIX
  • Subsystem: os
const os = require('os');
const assert = require('assert');

const ifconfig = os.networkInterfaces;
const baseline = ifconfig();
for (var i=0; i < 100; i++)
  assert.deepStrictEqual(baseline, ifconfig());

produces this error:

assert.js:60
  throw new errors.AssertionError({
  ^

AssertionError [ERR_ASSERTION]: { en0: 
   [ { address: 'XXXX',
       netmask: '60.160.15.255',
       family: 'IPv4',
       mac: '00:00:00:00:00:00',
      deepStrictEqual { en0: 
   [ { address: 'XXXX',
       netmask: '16.169.50.64',
       family: 'IPv4',
       mac: '00:00:00:00:00:00',

basically the netmask (and sometimes the mac value too) keeps changing.
