4.3billion computers seemed like it was enough when the world population was 3.6 billion. But then they started assigning /8 (16.8 million addresses) to companies like Ford Motors. Another 16.8 million addresses to represent loopback. IPv6 is assigned similarly like that, for example /64 (18,446,744,073,709,551,616 addresses) is the smallest allocation unit for SLAAC. I'm wondering when we will need IPv7.
