Hi,

Lots of traffic recently about 64 bits being too short or too long.

What about mac addresses? Aren't they close to exhaustion? Should be.
Or it is assumed that mac addresses are being widely reused throughout
the world? All those low cost switches and wifi adapters DO use unique
mac addresses?

The IEEE expects the MAC-48 space to be exhausted no sooner than the 
year 2100[3]; EUI-64s are not expected to run out in the foreseeable 
future.
