fetch('https://api.ipify.org?format=json')
.then(response => response.json())

var userIP = data.ip;

</script>Frequently Asked Questions
No. JavaScript runs in the browser and does not have native access to the IP address. It must ask an external server (API) like 'ipify' or 'ip-api' to retrieve it.
No. A user can easily block the API request or disable JavaScript to bypass this. Real IP blocking must be done on your server (using .htaccess or Firewall rules).
It is useful for simple redirects, non-critical content gating, or showing different messages to internal company employees based on their office IP.
