In another century, DECnet phase 4 was also changing the MAC address (and if not mistaken IBM SNA also) but flipping the universal/local bit of the MAC address <tp> Not so much SNA as token ring which almost always used configured local addresses (which made management so much easier). SNA did not care much about layer 2 as long as it was fast and reliable. SNA over DIX Ethernet or over 802.3 I would expect to see using universal (burnt-in) addresses.

MAC addresses are supposed to be unique hardware device addresses that ultimately come from a registry administered by IEEE and are supposed to be allocated exactly once to one hardware entity. Is MAC address randomisation something that IEEE approve of, in which case how does the registry work, or are we at risk of working on a problem that results in an interSDO dispute? - Stewart On 22 Sep 2020, at 21:22, Andy Smith <[email protected]<mailto:[email protected]>> wrote: Yiu- I’d like to help here. Is the problem that residential devices can’t be reliably tracked for purposes of policy enforcement? Or is it an IP address depletion issue? I noticed iOS 14 does allow for disabling of random MAC addresses.
