Web service to GeoIP [closed]

Question

Is there a reliable web-service that provides an API to turn an IP address into a location, i.e. city, region, country. Willing to pay, but need something solid and reliable.

Answer 1

My service, http://ipinfo.io includes location information, hostname, network owner and some other details:

$ curl ipinfo.io/8.8.8.8
{
  "ip": "8.8.8.8",
  "hostname": "google-public-dns-a.google.com",
  "loc": "37.385999999999996,-122.0838",
  "org": "AS15169 Google Inc.",
  "city": "Mountain View",
  "region": "CA",
  "country": "US",
  "phone": 650
}

Here's a PHP example:

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
echo $details->city; // -> "Mountain View"
