So now that you both agree that the second-least significant bit in the first
byte indicates a locally administered ethernet address, could you explain why
the following manufacturers have been assigned address blocks with this
"locally administered" bit set? (I can understand the DECNET logical address,
since it's derived from the DECNET node number, which is locally administered,
but the others escape me).
