Sorry, but containerization and SDN needs addresses. I can spawn dozen of networks on my computer using docker/flannel/kubernetes, but I have only 1 white IPv4 address for all of them, so I need to use NAT and step-stone server. I have no such limitation with IPv6: each host has it own white IPv6 address and addressing becomes flat. Sorry, but I have no choice, so I use IPv6 today.
