> - I saw that `10.0.0.3` showed up as a client on my switch with a randomized MAC address (presumably, since I couldn't find the MAC prefix in a vendor list).

MAC address randomization is enabled by default on iOS: https://www.linksys.com/support-article?articleNum=317709

Thanks for reminding me of this. This is looking less and less malicious at this point as `10.0.0.3` is my phone (using AT&T, which is where all the traffic was destined).

That still seems like an awful lot of traffic for your phone to be using.

Do you mind sharing what gets you that kind of data usage? Just hours of FaceTime calling or something else?
