PHP class to get user IP.

After reviewing the code after a few years, I would not recommend the use of the class for a production site, as preference was given to headers easily manipulated by the user to get the IP.

If the reliability of the header from which the IP will be obtained is not guaranteed, it is better to use $_SERVER['REMOTE_ADDR'] directly or develop a custom solution.


This library is supported by PHP versions 5.6 or higher and is compatible with HHVM versions 3.0 or higher.


The preferred way to install this extension is through Composer.

To install PHP Ip library, simply:

composer require Josantonius/Ip

The previous command will only install the necessary files, if you prefer to download the entire source code you can use:

composer require Josantonius/Ip --prefer-source

You can also clone the complete repository with Git:

$ git clone

Or install it manually:

Download Ip.php:
