What are the limitations of using MAC addresses instead of IP addresses for tracking website visits in PHP?

Using MAC addresses for tracking website visits in PHP is not feasible because MAC addresses are not typically accessible from web browsers due to privacy and security concerns. Instead, it is recommended to use IP addresses, which are readily available and can be used to track website visits effectively. 

// Get the visitor's IP address
$ip_address = $_SERVER['REMOTE_ADDR'];

// Store the IP address in a database or log file for tracking website visits
