Google has released a Doodle video animation with Vint Cerf explaining basic DNS and IP address management of the Internet, the formation of ICANN, and the IANA transition.
It is a fun little video and certainly makes the whole issue seem very simple. Unfortunately, real life isn’t that simple. There is a lot at stake with the control of the unique identifiers on the Internet. There is lots of history and politics going on behind the scenes with these changes in the Internet governance structure and how DNS, IP addresses, and other aspects of the Internet are managed.
