Disabling Private Address is easy. Follow Apple’s instructions below to disable Private address for a network:
1. Open the Settings app, then tap on Wi-Fi
2. Tap on the information button next to a network (in this case, the network you’re connected to).
3. Tap on the Private Address toggle to turn it off, a privacy warning will pop up,and click on Rejoin.
To ensure this is done immediately, we recommend turning your WiFi off and on again.
Once connected back to our network using the hardware MAC address, all of your paid WiFi products or voucher codes will be applied to the device immediately and you will not be required to purchase a new WiFi service. If you’re using a Free WiFi service and have previously already submitted your data to get online, you will not be required to re-enter your data to authenticate to your service.
Doing the above will only change the Private Address option for the network you’ve selected, and will leave the Private Address feature enabled for all other networks on your device.
