If I'm allowed to subnet my single /64, then I'm still not using NAT. And as long as I don't go beyond /80, autoconfig can still work, at least on ethernet -- which is pretty much 99.999% of cases. (not that I advocate the use of autoconfig. *grin*)
Sorry, Ricky. But that won't work. EUI-64 is required for autoconfig, and it expands the 48 bits to 64 bits by inserting FFFF or FFFE depending on if the original is a MAC-48 or EUI-48 identifier.
I think Ricky's point is that he could do autoconfig in a /80 as long as there isn't the semi-gratuitous MAC-48->EUI-64 expansion.
