Problem is that most of us have ethernet hubs rather than true IP
switches. If we had real IP everywhere we could deprecate MAC
addresses.
Except that we derive self-assigned IPv6 addresses from MAC addresses.
If we didn't need them to be MAC addresses we could go to EUI-64 and
have 16 shiny new bits to play with.
*You* wouldn't get to play with them; MAC vendors would. How would that
help, given they're already intended to be unique?
I don't want a unique identifier associated with my machine going on the wire.
Use RFC7217. Linux is in the process of defaulting to it.
Thanks,
I was one of the first people arguing that WiFi devices should declare
a random MAC address. The idea of putting permanent linkable
information on the wire is an abomination.
+1 -- nice to hear that! (and that's even worse when you do that in a
layer-3 address).
Thanks!
