title: laravel 4 saving ip address to model
body: <p>I'm trying to save a user ip address to my database using Laravel 4.
  I found the following function which returns a string </p>
  
  <pre><code>Request::getClientIp()
  </code></pre>
  
  <p>How would I store this in my model? Just a string or is there a more efficient way?</p>
  
  <pre><code>$table-&gt;string('ip_address');
  </code></pre>
