Hi Andy,

Happy to have you to help.

There exists applications that make assumption of the static mac-address and rely on the static mac-to-ip mappiing. For example: common implementation of sticky dhcp relies on static mac-address. Also, some community wifi implementations rely on static mac-address once the device is authenticated. At this stage, we are gathering use cases and interests of working together for this domain. The goal is to document the potential impacts and propose any best practice for transitioning IP applications to dynamic mac-address.

Best,
Yiu

Yiu-

I’d like to help here.   Is the problem that residential devices can’t be reliably tracked for purposes of policy enforcement?     Or is it an IP address depletion issue?

I noticed iOS 14 does allow for disabling of random MAC addresses.
