IPv6 is the next generation of the Internet Protocol (IP) address standard that will supplement and eventually replace IPv4, the protocol many Internet services still use today.

The Internet Society is highly involved in all aspects of IPv6, from its ongoing technical work in the Internet Engineering Task Force (IETF) to increasing its real-world deployment with the help of our Deploy360 Programme.

Deploy360 provides hands on, technical deployment information to network operators responsible for implementing new technologies and standards on their own networks.

Most of our IPv6 work is found directly in the Deploy360 IPv6 section. See the Featured Resources box above for a quick start.

World IPv6 Launch and World IPv6 Day

2011 – World IPv6 Day – the “24-hour test”

On June 8, 2011, top websites and Internet service providers around the world, including GoogleFacebookYahoo!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 were well-positioned for the move to a global IPv6-enabled Internet.

2012 – World IPv6 Launch

One year later on June 6, 2012, (“6/6” in most date systems), thousands of website operators, network operators, and device manufacturers came together to declare that IPv6 is “the new normal” and that their sites, networks and devices would operate over IPv6 from that point forward.

A record of that event can be found on the site: https://www.worldipv6launch.org/

In the years since the 2012 launch the growth of IPv6 usage continues at a strong rate. You can view ongoing statistics at:

IPv6 is now the new normal – and the resources found here on our site can help you make sure your networks and systems work with today’s IPv6 Internet.

6th Anniversary of World IPv6 Launch

On June 6th, on the sixth anniversary of World IPv6 Launch, we shared an updated report on the State of IPv6 Deployment in 2018. It really is staggering how far IPv6 deployment has progressed in six years.

To help showcase the progress made in the six years since World IPv6 Launch we are sharing:

– an updated report on the State of IPv6 Deployment 2018
– an infographic that clearly shows the scale and scope of IPv6 deployment
– and a fun quiz for you to test and share your knowledge of the State of IPv6 Deployment

On the sixth anniversary, Vint Cerf, co-designer of the TCP/IP protocol and a “Father of the Internet”, sent us this video message to share with you all:
