It appears that jsonip.appspot.com is over quota. What alternatives do you have?
- http://jsonip.com/
- http://freegeoip.appspot.com/ – This one is currently over quota as well
Have another? Post it below!
Or, Write Your Own with PHP:
<?php
$ip = !empty($_SERVER['REMOTE_ADDR'])?$_SERVER['REMOTE_ADDR']:'';
$json = array();
$json['ip'] = $ip;
if(!empty($_GET['callback'])){
//remove non standard characters if callback is set
$callback = preg_replace('#[^a-zA-Z0-9\-\_]#','',$_GET['callback']);
}
if(!empty($callback)){
//if callback still exists after cleaning up non standard characters
//then call that function with the IP data
echo $callback.'('.json_encode($json).');';
}else{
//else echo the IP data
echo json_encode($json);
}
?>
Note: It is important to put this on a FAST server otherwise your webpage might hang when loading, especially if you are using the a doc-ready syntax for javascript.
Have improvements? Post them below.
Remember to double-check that $_SERVER['REMOTE_ADDR'] honours X-forwarded-for headers or you’ll end up logging the wrong ip address for users behind proxies (including your own if you are using load-balancing reverse proxies)
Very true. Do you have an example of the best way to check the real remote address in php?
