The randomised MAC addresses of iPhones are from the 'locally
administered' MAC address ranges. The non-local non-multicast
addresses have a first octet of x0, x4, x8 or xc, where x is
any hex digit.

The locally administered addresses have a first octet of x2, x6,
xa or xe (like 76:f9:76:17:f6:4d, from my iPhone).

The iPhone MAC address fudging can be turned on/off for each network
separately, from the 'i' menu of the WiFi connection. Just tell your
folks to turn off the fudging for your network or stay outside.
