Disable Private Address
Enabling the private address makes your device more secure by limiting the tracking functionality when connecting to different Wi-Fi networks. This makes you less traceable across the network by websites and services.

The Private Address feature was added with the launch of iOS 14 and is enabled by default in your device. To disable this:
