title: Loopback get IP address from operation hook
body: <p>Well, that XD, how do I get the IP Address of the querier (if that's even the word xD) from within an operation hook? or a remote hook? (I can save it with <code>loopback.getCurrentContext()</code> to use on the operation hook).</p>
  
  <p>Say:</p>
  
  <pre><code>Model.observe('loaded', function(ctx,next) {
     ctx.ip ??
  });
  </code></pre>
