Any stack can use that (actually Linux, XP, Vista, KAME all have it). That is just RFC3041 and those are FULL EUI-64 addresses. > If the spec > had been different way back when, these could equally have been 32 or > 48 bits instead. But it wasn't. The specs just talk about EUI-64. Ethernet is just one thing that can be converted to a full EUI-64 address. Greets, Jeroen
