title: Why does ImagesService always return urls with ip 0.0.0.0 in development?
body: <p>Does anybody know why ImagesService.getServingUrl() from Google App engine SDK (1.6.0) always returns 0.0.0.0 in url in development enviroment ? How can I change it ? Initially I thought it depends on binding IP for DevServer which I pass in "--address" parameters but it turns out it's not the case.</p>
  
  <p>This is problem for me because I can't fetch image from <a href="http://0.0.0.0/" rel="nofollow">http://0.0.0.0/</a> on Windows 7 machine. But I know it works on Mac.</p>
  
  <p>Plus I'd like to be able to test my GWT app from another machine in the network therefore I'd like to bind to IP other than localhost.</p>
  
  <p>Because of it I have to string.replace() "0.0.0.0" with my real ip which kinda lame :)</p>
  
  <p>Thanks!</p>
