Note:  I learned recently that it's NOT necessarily true that a device's MAC address will remain static.

I was having trouble getting my Samsung phone to connect to my IFD, and finally figured out that it had a "MAC randomization" setting that defaulted to "on", apparently for privacy/security reasons.  Once I disabled that setting, I was able to see the phone's MAC address properly and allow it permission in the IFD to connect.

I'm hoping someone from Avidyne can chime in with some insight on something I've been curious about...

In 10.3 when you connect a mobile device like an iPad to the IFD, you have to go into user settings on the IFD, locate the device in the list, and set it to ALLOW. But the devices in the list are listed by their I: address.....which will potentially change when they connect on a different flight.

So the question is, when you ALLOW a device, is the IFD really only remembering the IP address to allow, or is it behind the scenes remembering the MAC address of the device and allowing that? The MAC would remain static, so even if the IP address changed, the IFD would still be able to identify and allow the mobile device without user intervention.

Thanks!
