About

This WordPress code snippet enhances the admin dashboard by adding a custom item to the WordPress admin bar labeled "Check External IP". This feature allows administrators to fetch and display the external IP address of the server hosting the WordPress site with a simple click. It's designed to provide convenience for administrators, especially useful in scenarios where knowing the external IP address is necessary for troubleshooting, configuration, or security purposes.

How to Setup Snippet

Viewing the External IP: Once implemented, administrators will see a "Check External IP" item in the WordPress admin bar. Clicking this item will trigger an alert dialogue that displays the current external IP address of the server. Security and Privacy: This feature is secure and respects privacy by limiting access to administrators and not displaying the IP address until explicitly requested. The code snippet utilizes api.ipify.org, a simple and straightforward external service, to fetch the external IP address of the server where the WordPress site is hosted. This is a free API and you should visit their website for more information.
