Yesterday, the Internet Society began the transition from IPv4 to IPv6. Currently we are using IPv4, the system that assigns a series of four numbers to each device. IPv4 only allows for about 4 billion addresses and the Internet needs more room than that. IPv6 is the new version of the Internet Protocol and expands the number of available addresses to a virtually limitless amount - 340 trillion trillion trillion addresses.
You don't need to prepare anything for IPv6; your applications and devices will work just as they did before. 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.
To find out whether you are already using IPv6, 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.
