However, should a user enable Daily MAC Address rotation, troubleshooting a client historically or looking at network analytics for a specific client would be much more challenging. Wi-Fi Analytics and Troubleshooting – With the current default behavior we should not be too worried about randomized MAC addresses for analytics, unless a client is switching SSIDs frequently, in which case it will be more difficult to identify SSID hopping.
DHCP Lease time should not be higher than 24 hrs, rather aiming at the lower timers. DHCP Servers – It is probably time to start using shorter DHCP lease timers, just to be safe whenever somebody decides to turn on periodic MAC rotation.This however goes against the original notion of “more privacy with random MAC enabled”. A potential long term solution to this issue would be to move to Hotspot 2.0, which not only provides a secure end-to-end communication for the user and automated network discovery, but also a more granular user-based identification.
This however is changing with the upcoming release of iOS 14 / WatchOS 7, Android 10+, and even a few recent versions of Windows 10. During association, a device would have used its “real” hardware MAC address. It has existed for several years and involved randomizing client MAC addresses when sending Probe Requests to prevent location tracking of devices that are not associated to the network.
Scroll down and the MAC address is the Wi-Fi Address.But for each device that number is unique. Unlike the MAC address, which will never change on your device, you might receive a different IP address each time you connect to the network. The IP address is your unique network identifier when you’re accessing the Internet here at UC Davis. 00:00:00:00:00:0X) for a specific piece of hardware, such as the network adapter located in WiFi devices. The Media Access Control (MAC) address is a unique 12-character identifier (e.g. How do I find the wireless IP address and/or MAC address for my iOS (iPhone/iPad) device? Overview
