title: How can I determine if an organization is using NAT?
body: <p>As far as I understand, I can tell if an organisation is using NAT if they are using private IP address space.</p>
  
  <p>It can be determined that an organization is using private IP address space if its addresses fall into the following ranges, reserved for private uses by Internet standards groups:</p>
  
  <ul>
  <li>10.0.0.0 through 10.255.255.255</li>
  <li>169.254.0.0 through 169.254.255.255 (APIPA only)</li>
  <li>172.16.0.0 through 172.31.255.255</li>
  <li>192.168.0.0 through 192.168.255.255 </li>
  </ul>
  
  <p>Am I correct.....? Please correct the logic if it is not correct.</p>
