Michael, allow me following up my own email. Re the question about
implementations of IPv6 over Firewire, I wanted to refine it.
I think some implementations of IPv6 over Firewire may still waste these
fffe bits, still questioning the point of 64-bit EUI-64 (instead of say
48bit).
(googling some earlier discussion on web [*]):
$ ifconfig fw0
^^^
fw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 2030
inet6 fe80::21c:b3ff:fe7c:d17a%fw0 prefixlen 64 scopeid 0x5
^^^^^
lladdr 00:1c:b3:ff:fe:7c:d1:7a
^^^^^
The refined question would thus be: would there be some IPv6 over
Firewire implementation which wouldn't waste these fffe bits?
(sorry for the questioning style of mails, I'm just humbly trying to see
whether I'm completely off with these fffe lost bits).

IEEE tries to have them all 48bit. Even non-IEEE (like USB) tries to

Have you ever heard of EUI-64?
<http://standards.ieee.org/regauth/oui/tutorials/EUI64.html>
Well yes, good pointer.
One notable IEEE protocol which uses EUI-64 is Firewire (IEEE 1394). For
more info see RFC 3146.
Thanks for this pointer too. I must ack I've not experimented IPv6 nor
IPv4 over Firewire. Are there some implementations of IPv6 over Firewire?
