When the Internet launched operationally in 1983, no one ever dreamed that there might be billions of devices and users trying to get online. But like a telephone network that is running out of phone numbers, the current Internet is running out of IP addresses, and if we don’t roll out Internet Protocol v6 (IPv6), we won’t have the room we need to grow and the Internet would become tangled, unsafe and unsustainable.
