Every network interface (wired or wireless) on every networked device in the world is assigned a unique 48-bit identifier—the MAC address—burned into its ROM at manufacturing time. While it’s often (usually?) possible to change this via the software driver, nobody thought of it as a big deal.
Until recently, when certain, ahem, spying revelations have woken people to the privacy implications of being able to track a machine, particularly on wi-fi networks, based on its unique MAC address.
And so some folks at the Internet Engineering Task Force have been doing experiments to determine whether randomly changing these addresses would cause hiccups for any network protocols. The good news is that the answer so far seems to be “no”.
