title: Express.js req.ip is returning ::ffff:127.0.0.1
body: <p>I am currently trying to get the IP of the requested user. The problem is the IP is returning <code>::ffff:127.0.0.1</code> instead of <code>127.0.0.1</code>. I tried using <code>trusted proxy</code> option (though not using a proxy) and the <code>req.ips</code> is blank. Using 4.x Express.js.</p>
  
  <pre><code>router.get('/', function(req, res, next) {
      console.log('ip', req.ip)
      res.send({})
  });
  </code></pre>
