On June 8, 2011 Cybera celebrated World IPv6 Day by providing you with a little more information about IPv4 and IPv6. When you first reached our site, you probably noticed a pop-up that was not there before, which we created specifically to either educate you about the switch to IPv6 or congratulate you for being a part of the future of the internet. For more information about how and why you should switch to IPv6, read our news release. To find other organizations using IPv6, visit the World IPv6 Day site.
When the internet was first created, four billion Internet Protocol (IP) addresses seemed completely sufficient, as no one could predict the kind of growth the Internet would experience. In the early 1990s, it soon became apparent there were not enough IP addresses, and scientists began working on the next step: IPv6. It supports approximately 340 undecillion unique addresses, which should hopefully be enough for the foreseeable future.
It is still early in adoption, but more organizations are switching to IPv6, including Cybera, CANARIE, and the other Optical Regional Advanced Networks (ORANS). The American Registry for Internet Numbers (ARIN) suggests all Internet servers should be prepared to serve IPv6-only clients by January 2012, although there will be ongoing support for IPv4.
