[afripv6-discuss] What are the benefits of IPv6 over IPv4

[Kivuva]

Kondwani, you are right. What about issuing a /8 class A IPv4 for
private addresses, or issuing /8 for several legacy companies. That is
16.7million or 2^24 hosts per company. Such a waste.

The same lack of foresight is seen in allocation of IPv6 by giving
small entities /48 (that is more than all addressable numbers in v4)
although that leaves us with 281 trillion /48.

Mark Elkins! Can someone enlighten me why a home may need a /60? Still
I don't see how we will exhaust v6 in our lifetime even after.
