DHCP Servers вЂ“ 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 вЂњmore privacy with random MAC enabledвЂќ. 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.

Guest Portals with MAC Registration вЂ“ Most Guest Captive Portals leverage MAC based registration to prevent frequent browser re-login and smoothen user experience by only requiring вЂњone time sign upвЂќ.If a user would enable daily MAC randomization (currently available on Windows and Android 11, and is turned off by default), a guest user would see a captive portal sign up page on a daily basis.

To overcome a ban, a user could just forget and rejoin a network to get a new MAC address generated, thus overcoming any restrictions.

Banned Client List вЂ“ Many InfoSec systems today rely on client banning or quarantine functions that are typically tied to a MAC address of a client.

Still, this is an item to consider in the future should random MAC rotation become a norm.

MAC Association Lists вЂ“ This is something customers should have planned to stop using a long time ago, enabling MAC randomization on a per SSID level today will not directly affect MAC ACLs functionality, unless a user would enable daily MAC rotation in the device settings.

The new MAC randomization algorithm applies to network connectivity and is now used for all communications. This problem can certainly be looked at from different angles (MAC Address from Google or AppleвЂ™s perspective provides different tracking options versus a typical enterprise or even a home user). The intent from device manufacturers like Google and Apple is to вЂњreduce a privacy riskвЂќ associated with an ability to track a device from a network usage or location perspective using a device unique MAC address. LetвЂ™s find out what these changes entail for enterprises and networking vendors. The new shift in the mobile device industry is to randomize MAC addresses not only during the network discovery phase, but also during association phase. 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 вЂњrealвЂќ 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. MAC Randomization is not a new term in the network industry.
