MAC addresses are allocated in blocks to manufacturers by the IEEE :=20
http://standards.ieee.org/regauth/

They will allocate you a block of 4096 addresses for the princely sum of =
$550...
https://standards.ieee.org/regauth/oui/forms/IAB-form.shtml

Or a manufacturer ID, giving you 2^24 addresses for $1650 :=20
https://standards.ieee.org/regauth/oui/forms/OUI-form.shtml

Not sure how they can justify charging this much to administer a list of =
numbers - nice work if you
can get it!

=46or a 1-off or low-volume product, these figures are pretty ridiculous,=
 and  you are highly unlikely
to have any problems just making one up.=20

Another approach to get a few guaranteed-unique addresses would be to =
pick up some old ISA ethernet
cards (a dollar or two at a computer junk sale) and 'transplant' their =
numbers....
