title: which app domain can I use for Facebook API
body: <p>I'm developing Django application and want to use Facebook API.
  I've registered the application at Facebook.</p>
  
  <p>And I want to test authentication of Facebook API by local developing environment before deploy at production server.
  I always start Django on local developing environment by
  python manage.py runserver 0.0.0.0:8000
  After that I can access my browser at <a href="http://192.168.7.38:8000/" rel="nofollow">http://192.168.7.38:8000/</a> for example.</p>
  
  <p>But I can't register the testApp at Facebook.
  On settings I must register App Domains and Site URL.
  I registered
  App Domains : 192.168.7.38
  Site URL : <a href="http://192.168.7.38:8000/" rel="nofollow">http://192.168.7.38:8000/</a></p>
  
  <p>But when I registered App Domains , error occured.
  'App domains must match the domain of the Secure Canvas URL, Mobile Site URL, Unity Binary URL, Site URL or Secure Page Tab URL. Please correct these domains: 192.168.7.38'</p>
  
  <p>What can I register App Domains?
  Sorry for my poor English.Thank you. </p>
