title: Setup to get city by IP number with Geokit
body: <p>I have a Rails 4 app deployed on Heroku.</p>
  
  <p>I have a method that decode an <code>ip</code> number to it´s <code>city</code> equivalent.</p>
  
  <p>From what I've understood there are a bunch of pitfalls when geocoding, i.e. reaching request limit on shared ip, unupdated geocode providers etc.</p>
  
  <p><strong>If someone has any recent experience of any similar user case as the one described above, it would be much appreciated to learn what setup works (if at all) best.</strong></p>
