Instead of sending the actual hardware address to every network it scans, the iPhone generates a random, temporary MAC address for probe requests when searching for available Wi-Fi networks.

By navigating to the Wi-Fi settings, selecting the specific network, and toggling the "Private Address" option off, the iPhone can be configured to use its actual hardware address. By constantly changing the identifier, it becomes significantly harder for third parties to track your device across different Wi-Fi networks, such as in public spaces or commercial venues.
When randomization is active, the Source Address field will contain the spoofed value rather than the burned-in address. If you have configured your router to allow only specific devices based on their hardware addresses, the randomization feature will cause an iPhone to appear as an unauthorized device.
