In your previous mail you wrote: The world has more devices than Ethernet. The Ethernet MAC -> EUI-64 trick (thus your lost fffe bits) is just a trick. Take firewire for example which uses full EUI-64. => hum, unfortunately Firewire is the bad example: it uses EUI-64 for IDs, address

For what it's worth, Whenever statelessly auto-configuring an IPv6 address on Ethernet the 10th and 11th bytes are always 'fffe', hardcoded. These are lost bits. Alex Dunn, Jeffrey H. wrote: TJ, I am not sure what point you are trying to make. I never said any bits were "lost," just that
