Find My External Public IP Address

See more HTTP Examples

To find your external public IP address (not your LAN IP address, such as 192.168.1.* or 172.16.16.*, etc), your application would need to send a request to an HTTP server that can report back on the origin IP address. You can easily write a simple script on your own web server to do it, or you can use a service such as ipify.org.

This example shows how to send a request to the ipify.org endpoint to get your public IP address.
