title: how to get browser's remote ip by javascript?
body: <p>I want to obtain the remote client ip by javascript, not querying any external ip resource pools. how could i get the remote ip address, just like the way i get appName by <code>navigator.appName</code> </p>
  
  <p>also like the ways as follows:</p>
  
  <p>PHP:<code>&lt;?php echo $_SERVER["REMOTE_ADDR"]; ?&gt;</code></p>
  
  <p>NODE.JS: <code>req.connection.remoteAddress</code></p>
  
  <p>so green with javascript, and im trying to google with some keywords. yet i still can't find the result i want. any guy here could share his solution of the same desired scene? any tips or suggestions are welcome.</p>
  
  <p>platform:chrome, firefox</p>
