Vint Cerf, Chief Internet Evangelist at Google, and a founding father of the Internet, discusses the next version of the Internet, IPv6, and why we need it.
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. World IPv6 Launch on June 6, 2012, marks the start of a coordinated rollout by major websites and Internet service and equipment providers. As for as users goes you don’t need to prepare anything for IPv6; your applications and devices will work just as they did before. This change is to make sure you can keep using the Internet in the future just as you do today. The complete transition to IPv4 to IPv6 will take time as every website and Internet Service Provider must make the switch. In the meantime, both systems will work together until IPv4 is no longer needed. You may be using IPv6 already, visit ipv6test.google.com to find out. Many devices you use already support IPv6; however, the websites you visit and your Internet Service Provider must first enable IPv6 before you can use it. Finally are you wondering where is IPV5, hmm good question but Version 5 was reserved for the Internet Stream Protocol developed prior to IPv6–it was never widely deployed and will not be used publicly.
