The address space is daunting in scale as you have noted, but I don't see any lessons learned in address allocation between IPv6 and IPv4. Consider as a residential customer, I will be provided a /64, which means each individual on Earth will have roughly 1 billion addresses each. Organizations will be provided /48s or smaller, but given the current issues with routing /48's globally, I think you will find more organizations fighting for /32s or smaller... so what once was a astonomical number of addresses that one cannot concieve numerically, soon becomes much smaller. I can see an IPv7 in the future, and doing it all over again... I just hope I retire before it comes... The only difference I can see between IPv4 and IPv6 is how much of a pain it is to type a 128 bit address... Just like back in the day when Class B networks were handed out like candy, one day we will be figuring out how to put in emergency allocations on the ARIN listserv for IPv6 because of address exhaustion and waste.
I'm perplexed. At what size address would people stop worrying about the "finite" address space? 256 bits? 1024 bits? I just don't get it. It's not like people get stressed out about running out of name space in English which is probably more "finite" than ipv6. Mike
