@kkarhan @landley @jschauma @ryanc @0xabad1dea "still, a #64bit #AddresaSpace would've been more than sufficient". Yes, the famous "640KB should be enough for everyone". "A #128bit address space is quite inefficient" Why/where/how inefficient? Do DFZ routers have problems? Is storage SO constrained nowadays that we can't store 128bits values? Or is this again the revenge of "oh my god IPv6 is so difficult, I can't remember all those long addresses like I did in IPv4"?
