title: Is given IP address assigned to some Wi-Fi Hotspot?
body: <p>I'm doing a project: the goal is to find features detecting a hotspot, but I have no training set or test set for development and estimation of methods yet.</p>
  
  <p>As far as I understand, there are 2 ways to build the sets:</p>
  
  <ul>
  <li>to get a list of some of U.S. hotspots;</li>
  <li>to find a function that checks if given IP address is connected with some hotspot (with some measure of certainty).</li>
  </ul>
  
  <p>So what I wonder:</p>
  
  <ul>
  <li>is there any U.S. Hotspots IP dataset?</li>
  <li>are there any other ways or technologies to find out whether a given IP address is assigned to a Hotspot?</li>
  </ul>
  
  <p>Any helpful ideas appreciated (criticism is appreciated too).</p>
