title: Node.js : know what subnet(s) i'm on?
body: <p>I already found ways to get the network addresses with Node.js (using <code>require('os').networkInterfaces()</code>).</p>
  
  <p>But does somebody know how to find which subnet(s) (<code>/24, /16, /8</code> ...) I'm on?</p>
  
  <p>The project involves scanning my own subnet using <code>evilscan</code>;-)</p>
  
  <p>I'm using OS X</p>
  
  <p>Thanks</p>
