What are the limitations of using Java or Flash to retrieve internal IP or MAC addresses?

Using Java or Flash to retrieve internal IP or MAC addresses can be limited due to security restrictions imposed by modern browsers. These restrictions prevent these technologies from accessing such sensitive information for privacy and security reasons. To overcome this limitation, you can use server-side scripting languages like PHP to retrieve the internal IP address of a user. 

<?php
$internalIp = $_SERVER['REMOTE_ADDR'];
echo "Internal IP Address: " . $internalIp;
?>
