What is the LAN address of iPhone? What is it used for?

To help protect user privacy, iPhone uses a unique private network address, called a Media Access Control (MAC) address, on each Wireless LAN it joins. Using a private address can help reduce tracking of your iPhone across different Wi-Fi networks.

##About the private wireless LAN address:

To communicate with a wireless LAN, a device must identify itself on the network using a unique network address, which is called a media access control (MAC) address. If a device consistently uses the same Wireless LAN MAC address on all networks, over time, network operators and other network observers can more easily associate this address with the device's network activity and location to conduct some kind of user tracking or analysis , and this applies to all devices on all wireless LANs.

On iPhone, when you turn on "Private Addresses" for supported networks, your device can be updated by using a different MAC address on each wireless LAN. Protect privacy well. This unique MAC address is your device's private wireless LAN address and is used only on that network.

Turn on "Private Wireless LAN Address":

Apple official recommendation is that in order to better protect personal privacy, "Private Wireless LAN Address" can be turned on for all supported networks.

Users can go to Settings-Wireless LAN, then tap the "i" next to a network and turn on "Private Wireless LAN Address".

If the network cannot use a private address (such as to provide parental controls or identify the iPhone has been authorized to join), or if the network cannot be used normally after being turned on again, you can stop using the private address for the network.
