Apple made a change to iOS 11 which has impacted millions of iPhone users’ who use mobile apps to secure and troubleshoot their network.
With iOS 11, Apple has blocked third-party developer access to MAC addresses. Network utility apps such as Fing, NetAnalyzer, iNet and IP scanner used this information to let users see all the devices connected to a WiFi network.
On iOS 11 users can no longer use a third-party app to identify and recognize which devices are connected to their network. They can also no longer easily detect a device’s online/offline status.
