Today is the 
World IPv6 day or "Test Flight" day and the goal of the Test Flight Day 
is to motivate organizations across the industry – Internet service 
providers, hardware makers, operating system vendors and web companies –
 to prepare their services for IPv6 to ensure a successful transition as
 IPv4 addresses run out. 
 
Including Google, Facebook, Yahoo!, Akamai and Limelight Networks will offer their contents over IPv6 for 24 hours. 
 
You can check your IPv6 through the <a href="http://lm.facebook.com/l.php?u=http%3A%2F%2Ftest-ipv6.com%2F&h=dAQEBlw_3&s=1" rel="nofollow" target="_blank">http://test-ipv6.com/</a>. 
 
Google has announced that if any problem occured to visit Google then they recommend to use ipv4.google.com rather using <a href="http://lm.facebook.com/l.php?u=http%3A%2F%2Fwww.google.com%2F&h=TAQEEBq0U&s=1" rel="nofollow" target="_blank">www.google.com</a> on june 8. 
 
Although
 you havent IPv6 , its not problem because they are not going to 
completly cwitch to IPv6 , They going to use both IP versions for the 
users on 8 th of june.

 along with Google, Yahoo!, Akamai, Limelight Networks, and the Internet
 Society. June 8, 2011, will be the first global-scale "test flight" of 
IPv6, the next generation protocol for the Internet. And best of all, 
it’s open to everyone who’s interested in testing their IPv6 service. 
 
This
 is a big step forward for the Internet because the current protocol, 
IPv4 (also known as IP), will run out of addresses this year. Since 
every endpoint on the Internet — whether it’s a computer, mobile phone, 
or TV — relies on a unique IP address to communicate, we need more 
addresses so they can all stay connected. 
 
As a next 
generation protocol, IPv6 provides a vast number of addresses by today's
 standards — 4 billion times the number that are available under IPv4. 
Telecom carriers, ISPs, OS makers, hardware manufacturers, Web 
companies, and governments around the world are depending on IPv6 to 
continue growth of the Internet. World IPv6 Day — a 24 hour period 
during which Internet companies will test IPv6 — is an important step 
that enables the technology to move forward in a globally coordinated 
setting. 
 
Testing IPv6 is important because recent studies 
indicate about 0.05% of Internet users (1 in 2,000) can’t reliably 
connect to websites that enable both IPv4 and IPv6 addresses (known as 
"dual-stacked" websites). This has resulted in a classic chicken-and-egg
 puzzle right now: websites don’t want to enable IPv6 because a small 
number of their users may have trouble connecting. At the same time, 
doing nothing means that ever more users will have trouble connecting to
 these dual-stacked websites, and ISPs will turn to less effective 
technical alternatives like Large Scale NAT (see below). 
 
To
 break this conundrum, we need to take a small, concerted step for just 
24 hours, where Web companies, ISPs, hardware/software makers, and users
 work together and synchronize plans, communication, and support. 
 
Why IPv6 Is Important to Facebook 
The
 switch to IPv6 is especially important for us at Facebook as we pursue 
our mission of helping the world connect and share online. Since last 
summer, we’ve offered Facebook over IPv6 at <a href="http://www.v6.facebook.com/?refid=22" rel="nofollow" target="_blank">www.v6.facebook.com</a>
 (addressed 2620:0:1cfe:face:b00c::3 in true hexadecimal IPv6 hacker 
fashion; note that the v6 link works only from IPv6 endpoints). World 
IPv6 Day will allow us to test our infrastructure and code more widely 
with low risk to our service and users. 
 
The day also 
promotes awareness among hardware and software suppliers, and should 
encourage everyone to create robust IPv6 products and fix buggy ones. 
Between now and June 8th, there’s an opportunity for the entire industry
 to ensure hardware and software isn’t just IPv6-capable, but that it 
can reliably connect people to dual-stacked websites. 
 
This
 year's exhaustion of IPv4 addresses isn’t exactly a sky-is-falling 
situation, because there are always economic and technical solutions 
when there's enough energy put behind a big problem. An economic 
solution is for organizations to buy IPv4 addresses from others willing 
to sell them. But this isn’t a sustainable solution, and it’s perhaps 
not completely fair when you consider how the Internet has historically 
been fully open and accessible. On the technical side, there are many 
protocols and devices in different stages of maturity. But some v4-to-v6
 transitional protocols are so old they are nearly phased-out or 
obsolete. 
 
LSN: A Technical Alternative 
One
 newer solution being proposed is Large Scale NAT (Network Address 
Translation) or LSN, also called Carrier Grade NAT. NAT basically 
translates one address into another, typically a private address into a 
public address and vice-versa. Many users and sites do this today on a 
small scale. Your laptop may have the private address 192.168.1.10, 
which is translated by your home router into a public address provided 
by your ISP. The public address is unique and the address you depend on 
for global Internet connectivity. So what happens when your ISP runs out
 of addresses? Before address exhaustion, it would simply apply for and 
receive new addresses. But that is no longer the case.

Enter
 LSN. The plan here is to give your endpoint, like your home router, a 
private address instead of a public one and then translate your traffic 
at a new, heavy-duty LSN device that lives elsewhere on the Internet. 
Thus, your laptop's private address will be translated to another 
private address at your home router, which will then be translated again
 into a public address at this new LSN device. Thousands of users share a
 single IP address thanks to the massive translator. What’s unclear is 
whether this will give us the same performance, reliability, and 
security we have on the Internet today. And the people deploying LSN are
 not exactly thrilled about having to use it — it's more out of 
necessity because most websites aren’t yet dual-stacked to handle an 
end-to-end IPv6 connection. 
 
IPv6 vs. LSN 
Many
 people have spent years working IPv6, which is a longer-term and more 
reliable solution than LSN. Adopting IPv6 means that people with IPv6 
addresses can talk to IPv6-enabled, dual-stack sites without 
translators. The following chart describes some other aspects of LSN 
compared to end-to-end IPv6 connectivity.

We
 hope you'll follow along in the coming months and then join us for 
World IPv6 Day on June 8, 2011, when the Internet takes a big step 
forward!
