title: Vagrant, Flask — App not running on 10.10.10.10, 127.0.0.1
body: <p>I'm running an app on my local box via Vagrant. The Python/Flask app launches and prints:</p>
  
  <p><code>* Running on http://127.0.0.1:5000/
   * Restarting with reloader
  </code></p>
  
  <p>I found this <a href="https://github.com/makersquare/student-dev-box/wiki/Using-Vagrant-for-Development#testing-web-based-applications-in-vagrant" rel="noreferrer">https://github.com/makersquare/student-dev-box/wiki/Using-Vagrant-for-Development#testing-web-based-applications-in-vagrant</a>
  which suggests that Vagrant apps run on <code>10.10.10.10</code> (not <code>127.0.0.1</code>), but when I navigate to that IP address (port 5000), I get the same result: "This webpage is not available".</p>
  
  <p>Question: my app is running, but on what IP address? I can't seem to find it. Do I need to modify some configuration files?</p>
  
  <p>Thanks in advance.</p>
