title: How to access/ping a server located on AWS?
body: <p>With what address should a server located on AWS be accessed?</p>
  
  <p>I've created an AWS instance and installed a web server on it. However the server is not reachable via any of the:</p>
  
  <ol>
  <li>ec2-174-129-24-92.compute-1.amazonaws.com</li>
  <li>the IP address from instance's <code>ifconfig</code></li>
  <li>an elastic IP address I've created on the AWS dashboard and associated with the instance</li>
  </ol>
  
  <p>Surprisingly, ssh with <code>root@ec2-174-129-24-92.compute-1.amazonaws.com</code> works fine.</p>
  
  <p>What might be the problem and how to bind an address to the instance?</p>
