title: node.js how to get external remote IP address of a web server - some page stackoverflow.com for example?
body: <p>by request.ip I can get IP of an client. But how to get external remote IP address of a web server - some page stackoverflow.com for example? Headers don't give me IP. On chrome developer tool - NETWORK tab I can see in 
  <strong>general</strong> HEADERS that it has:</p>
  
  <p><em>Request URL:</em></p>
  
  <p><em>Request Method:</em></p>
  
  <p><em>Status Code:200</em></p>
  
  <p><strong>AND</strong>
  <em>Remote Address:<strong>67.138.5.12:80</em></strong></p>
  
  <p>but as I said, I can't dig to it when I request headers. There must be other way since chrome got this. Maybe some dns calculation by dns page name (page name = this IP)?</p>
