> I'd like to reiterate that dual-stacking is an administrative pain... This professional administrator disagrees. > The sin in dual-stack IPv4 + IPv6 is that they're the same protocol. There is nothing different in their aims, their reach, their utility or their transit networks. That same commentary applies to IP + IPX. Your understanding of IPX is poor. This was about the depth of analysis I was expecting. Pity. > Eliminating MAC addresses is a novel idea. I have not seen it credibly suggested before. Surely some functionality would be lost? No more than eliminating IPv4 addresses in the far future, and far less if that elimination was done today. Go read up. It'll probably take you a few weeks to get up to speed. > But today, it is realistic to eliminate IPv4 just by widening support for v6. lol.
