Sadly, the only reference I have handy at the moment is a rather dryly written college text book sitting on my bookshelf. I can tell you that all versions of Windows have "let's naively use the MAC address to create our IPv6 address!!" disabled by default...-Innuendo (September 06, 2015, 01:59 PM)
Found the following:
Privacy extensions are enabled by default in Windows (since XP SP1), OS X (since 10.7), and iOS (since version 4.3). Some Linux distributions have enabled privacy extensions as well.
FWIW, was examining an Android device with Cyanogenmod 12.x on it, and for the one in question, the extensions didn't seem to be enabled as a portion of the mac address appeared to be easily readable off of the IPv6 address of a network interface.
