Well, my interpretation is that EUI-64s always have the universal/local
bit set to universal. And, non-EUI-64's have the universal/local bit
"set" to local. For local ones, I assume that the 'c' and 'm' bits are
"anything goes". The question then is whether the individual/group bit
applies.
If on
Also, the impact of assuming this individual/group bit exists is the
loss of 1 bit (so the "randomly" generated value only has 62 bits of
uniqueness rather than 63 bits). While that cuts the number of values in
half, there is still plenty of randomness.
I do think answering this question about "lo

Hmm; not exactly what I said, but in (RFC4214, Section 6.1),
what if we were to change:
"When the IPv4 address is known to be globally unique, the "u" bit
(universal/local) is set to 1; otherwise, the "u" b
