This addon for Node.js allows you to get the system's DNS configuration under Windows.

It doesn't work on *nix, where you can simply read /etc/resolv.conf to get the system's DNS servers.

This project is available on npm. Since it is a native (C++) addon, you'll need everything node-gyp needs to build projects, which includes Python 2.7 and MS VC++.

> npm install winnetinfo

1. var ni = require('winnetinfo');
2. ni.getNetworkParams();

You'll get something like this:

{ hostName: 'daguej',
  domainName: '',
  dnsServers:
   [ '8.8.8.8',
	 '8.8.4.4', ],
  dnsEnabled: false,
  nodeType: 4,
  domain: '',
  arpProxyEnabled: false,
  routingEnabled: false,
  dhcpScope: '' }
