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?
