Re: ipv4 vs 6 With IP it's a bit different: unlike network capacity, the number of IP addresses is a known quantity. IPv4 gives you, at most, about 4 billion IP addresses. Being that the population of the world is 7 billion, it's just not enough. We could delay the inevitable for a short time by reclaiming IP addresses, using more NAT, etc, but a 32 bit address space really is too small in an age when more and more people and devices are connecting to the internet.
