Does anybody know why anybody thought it was a good idea to put the extra bits in the middle, or for IPv6 to adopt them?"64bit MAC" -- which pretty much exists nowhere. It's a repeat of the mistakes from IPv4's early days: CLASSFUL ROUTING.Blame IEEE. They claimed that for identifying network cards 64 bit ID will be used in th future.... (Already used in IEEE 1394)
Even if that is true and doesnt require ethernet as we know it to be forklifted which may be enough to rule it out from ever happening (see 1500 mtu for reference), address auto configuration does not require 64 bits. Its just nicer that way.
What IEEE is concerned about is global uniqueness purity.Global uniqueness into perpetuity isnt required operationally on a lan, its just nicer that way.
Gateway directed auto-conf enable-able on any bit length, with icmp conflict detection seems no worse that what we have now with either dhcpv4 or apipa.
