I imagine the device is able to detect it is the same BSSID and determine the 
MAC does not need to be changed.

Nope. MAC addr is still the same. This is day 2. I’ve been associated to the

It really only impacts mid to long term guests. So I guess in your example, 
parents weekend may be the one that is affected. But even then, dropping the 
lease times would solve the problem. I believe many wireless vendors recommend 
a visitor lease time of 1-8 hours.

Tim,

With Covid, any lease time would not be an issue. But how big were your home 
football events / tailgate parties / parent weekends at Brandeis? I’m focusing 
more on the impact of those events on the guest side of things.

Agreed on IPv6, but even for IPv4, I imagine most folks are running short 
leases on a visitor network, so I don’t really think much changes here. If your 
leases are 12 hours or less, there should be no impact.

Pondering... that implies that a heavyweight roaming event could change the
MAC.

 If true, that implies the WiFi roaming architecture considerations is even
more critical unless change of MAC doesn’t matter to the overall system
design and app behavior (I.e multimedia activity while physically roaming)
