As IPv6 is set to grow in the coming few years, are you ready for it yet?
Want to find out your IPv6 readiness? Use this test.
IPv6 is an IP address standard designed to replace the current IPv4 protocol, which has been in use since the 1980s for routing Internet traffic. The new protocol has been available for several years now and supports several magnitudes more address spaces than IPv4, while also providing better security and reliability.
For more than 30 years, 32-bit addresses have served us well, but now the Internet is running out of space. IPv6 is the only long-term solution, but as the chart below shows, it has not yet been widely deployed. With IPv4 addresses expected to run out in 2011, only 0.2% of Internet users have native IPv6 connectivity:
On 8 June, 2011, top websites and Internet service providers around the world, including Google, Facebook, Yahoo!, Akamai and Limelight Networks joined together with more than 1000 other participating websites in World IPv6 Day for a successful global-scale trial of the new Internet Protocol, IPv6. By providing a coordinated 24-hour “test flight”, the event helped demonstrate that major websites around the world are well-positioned for the move to a global IPv6-enabled Internet, enabling its continued exponential growth.
Many of the problems are likely to stem from the simple facts that IPv6 is far newer and untested compared with IPv4, and that the two protocols will need to coexist for several years.
The real test of the IPv6 protocol, however, will come when companies start migrating to it in earnest in the next few years.
