Every device connected to the Internet must be uniquely identified, and this identification is made through the IP (Internet Protocol) address.
Free IPv4 addresses (IP version 4 - version of IP currently used) will be exhausted soon and to allow the continued growth of the Internet the IPv6 (Internet Protocol version 6) was developed.
The IPv4 and the IPv6 protocols are not compatible.
With a period of coexistence between the two versions, the transition will occur gradually by deploying the IPv6 without changing the working of the pre-existing IPv4 (Dual Stack). However, after the exhaustion of the IPv4, there will be users that will only have IPv6 available and will have trouble accessing IPv4 contents.
The World IPv6 Day was a worldwide test, performed on June 8, 2011, which content providers like Google, Facebook, Yahoo!, Akamai and Lamelight Networks, as well as Brazillian companies like Terra, Campus Party, iG, Dualtec and Nomer have agreed to make their sites available via IPv6 for 24 hours. Its main objective was to test the behavior of IPv4 users when browsing on IPv6 sites (Dual Stack), because it was feared that things like automatic tunneling, software bugs and other problems could hinder if a website implanted IPv6.
More information can be obtained on http://www.worldipv6day.org.
The initiative was a success. Many companies have joined and only very few users have had problems (0-0.02%), which many of them could solve the situation with simple instructions set found on the participant website. Among the participants, approximately 60% of the sites have kept the IPv6 enabled after the test period and, despite not having been the focus of the initiative, it was possible to notice a increase of the IPv6 traffic on the Internet.
To give the opportunity to the content providers that did not participate in the first test to do so. Moreover, a need of testing the IPv6 itself was noticed after the World IPv6 Day, so, in the IPv6 week, there will be:
The IPv6 Week is a major coordinated test of the new Internet protocol that will happen from February 6 to 12, 2012. During this week websites like Globo.com, iG, Terra, UOL and many others will be available in IPv6. Content providers will have users testing its contents, and companies will test their corporate networks.
The main objectives of the week are:
The intention during the IPv6 Week is that not only content providers will be participating, but also ISP's, companies/institutions and domestic users.

The IPv6 Week will take place from February 6 to 12 of 2012, at the same time of Campus Party Brazil 2012.
The list of participants can be found at http://www.ipv6week.org/WeekParticipants.html
No, the participants will not disable their IPv4, they will be working in dual stack, that is with both IPv4 and IPv6 working parallel. This way users that only have IPv4 access available during the IPv6 Week will still be able to use the Internet and accessing the content of the participants websites normally, and providers that will offer IPv6 access for their users will keep offering IPv4 access, allowing their users to keep accessing Internet places that still does not support the new protocol.
