One more thing,

They both use the same 24-bit OUI values. It looks to me like IEEE
decided to deprecate the name MAC-48. Why IEEE choose to have two
different ways to create EUI-64 from these 48-bit identifiers is a
mystery to me. As far as bits on the wire, EUI-48 and MAC-48
appear to be exactly the same. The link in Jinmei's email that
started this discussion confirms this:
"The distinction between EUI-48 and MAC-48 identifiers is purely
semantic: MAC-48 is used for network hardware; EUI-48 is used to
identify other sorts of devices and software. (Thus, by definition,
an EUI-48 is not in fact a "MAC address", although it is
syntactically indistinguishable from one and assigned from the same
numbering space.)"
I will still plan to submit the new text as it clarifies our use of
these identifiers.
On further thought, I will change the last paragraph of the Note to:
This document purposely continues the use of 0xFF and 0xFE
because it meets
the requirements for IPv6 interface identifiers (i.e., that they
must be unique on
the link), IEEE EUI-48 and MAC-48 identifiers are syntactically
equivalent,
and that it doesn't cause any problems in practice.
Let me know if anyone objects.
Thanks,
Bob
