There are 6.8 billion people on the planet.
Each will likely need at least one IP address and 5 is becoming a rough average.

This talk will delve into the reasons behind IPv6 and why IPv6 adoption has been slow until recently. We'll also talk about the looming implications for organizations that continue to procrastinate IPv6 deployment now that there is a strong upswing in adoption as we approach IPv4 free pool exhaustion.
