i got a problem with uniqueness of ipv6 address when it involves the MAC-address as a last 64 bit portion. By definition the MAC-addresses are globally unique, that is every network card manufactured have an unique ID which, when supplanted to the later 64-bit portion of the IPV6 makes it also unique. But proliferation of VMs with logical network IDs whose MAC addresses are assigned from random pool makes it not so so??
Also, when I inspect the portion of the ipv6 configured on the VMs that I installed, none of the ipv6 resembles the MAC of the interface. How come?
