title: Reliable API to determine an ip address's city and country
body: <p>I want a reliable API that can be used to determine a city and country from an IP address.</p>
  
  <p>My search on Google led to <a href="http://ipinfodb.com/ip_location_api.php" rel="nofollow noreferrer">http://ipinfodb.com/ip_location_api.php</a>. It seems perfect but my only concern is the reliability of this service. Does google have anything like this?</p>
  
  <p>I'm looking for free or paid APIs that help determine location from IP.</p>
