I want to replace http://www.wpfetish.com/ip2nation.php/?ip= with http://ipinfo.io/yourip_here/country

in this code to get country code

/*Uses WordPress HTTP Class*/
if( !class_exists( 'WP_Http' ) )
    include_once( ABSPATH . WPINC. '/class-http.php' );

$request = new WP_Http;
/*
 * get country info based on the ip of user
 * requests to the plugin server for ip to country code
 */
    $result = $request->request( "http://www.wpfetish.com/ip2nation.php/?ip=$user_ip" );     

if(!empty($result['body'])){
    $res = json_decode($result['body']);
    if($res->status == 'success'){
        return strtoupper( $res->iso_code_2 );
    }
}

return 'default';

}

You'll need to change a few other things, because http://ipinfo.io doesn't return a body or status field:

$ curl ipinfo.io/8.8.8.8
{
  "ip": "8.8.8.8",
  "hostname": "google-public-dns-a.google.com",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "loc": "37.3860,-122.0838",
  "org": "AS15169 Google Inc.",
  "postal": "94040"
}

And if you request just /country it doesn't return a JSON object:

$ curl ipinfo.io/8.8.8.8/country
US

So the full code you need is just this:

$request = new WP_Http;
$result = $request->request("http://ipinfo.io/$user_ip/country");     
return trim($result);

If you don't want to use WP_Http and want to check for some specific countries, here's the full code:

$user_ip = $_SERVER['REMOTE_ADDR'];
$res = file_get_contents("http://ipinfo.io/${user_ip}/country");
$country = trim($res);
if(in_array($country, array("GB", "US"))) {
    // User is in the UK or US
}
