title: Request.ServerVariables["REMOTE_ADDR"] gets IP6 instead IP4
body: <p>Here is my code:</p>
  
  <pre><code>string ip = Request.ServerVariables["REMOTE_ADDR"]
  </code></pre>
  
  <p>I use it for saving the <code>IP</code> for each login to a <code>UserLog</code> table.
  Poorly it saves the <code>IP6</code> instead of the <code>IP4</code>.</p>
  
  <p>What is the corret way?</p>
