How to Get the Client IP Address in Laravel without Falling Prey to Proxy Trickery?

Getting Client IP Address in Laravel 5

When attempting to acquire the client's IP address in Laravel, the $_SERVER["REMOTE_ADDR"] PHP function may inadvertently return the server's IP instead. To rectify this, Laravel provides a more robust method.

Laravel's IP Retrieval

Introducing Request::ip(), a Laravel function that effectively retrieves the client's IP address. Underneath the hood, it utilizes the getClientIps method from the Symfony Request Object.

public function getClientIps()
{
    // ... Symfony method implementation
}

This method considers trusted proxies, as evident in the headers and trusted proxy ranges configured in Laravel's request_config settings. Consequently, Request::ip() accurately obtains the visitor's IP address, regardless of intermediary proxies.

Therefore, to successfully retrieve the client's IP address in Laravel 5 , employ the following:

<code class="php">$clientIpAddress = request()->ip();</code>
