title: Apache Listen configuration
body: <p>What is the difference between the following configurations</p>
  
  <pre><code>Listen *:80 //anything at port 80
  Listen 192.168.0.34:80 //from an internal ip on port 80
  Listen 173.194.35.23:80 //from an external ip on port 80
  </code></pre>
  
  <p>Which of them is the best configuration (if there is any difference between them). I want my server to be accessed from internet not just from a LAN.</p>
