With the era of freely
available IPv4 addresses nearing its end, I'm pleased to see that 2012
appears to be the year when the IPv6
Internet will finally reach maturity and launch into wide-scale commercial
use. For over a decade, the groundwork
for the migration to version 6 of the Internet Protocol (IPv6) has been built,
with changes to operating systems, client and server software, routers, and
Internet backbone networks. To-date,
however, the availability of IPv6 content and end-users has remained slim with few Web sites
being available over IPv6 and with just over 0.5% of
global Internet users having IPv6 connectivity that their machines will elect
I'm optimistic that IPv6 adoption is on the verge of gaining real traction, and the upcoming World IPv6 Launch event on June 6th will be a milestone. As part of World IPv6 Launch, many large websites (including quite a few Akamai customer sites) are permanently enabling access over IPv6. In addition, some major ISPs are enabling IPv6 for over 1% of their end-users, and a few home router vendors are also enabling IPv6 by default in their products. A more complete transition is going to take well over a decade, but with IPv6 access for both more content and more end-users, we are making progress towards that goal.
Akamai is committed to helping our customers with a smooth transition to IPv6. We have had IPv6 capabilities for over a year and IPv6-enabled over 50 sites belonging to over 20 customers that participated in last year's World IPv6 Day event. In April 2012, we released production IPv6 support for many of our products and solutions, including Dynamic Site Accelerator, Terra Alta, and Kona Site Defender.
