The measurement activities below track different aspects of IPv6 deployment on the global Internet. The different measurements show various dimensions of the answer to the question of how broadly IPv6 is being used on the global Internet. The tables, charts, and links provide answers to questions such as: which websites have enabled IPv6, how many visitors to a specific website are using IPv6, how many networks have significant IPv6 deployment, and how much traffic at an Internet exchange is using IPv6?

Notes on network operator measurements

We present measurements of network operator participants in World IPv6 Launch, based on data received from major website participants, as described in more detail below. We present a simple average of the data received, and list all networks with measurements from at least two sources, with a simple average above 0.1%. The network operator participants list includes some networks that measured above the threshold leading up to June 6th 2012, but for which we have insufficient measurement data to list here.

Akamai: We are reporting adoption rates based on the percentage of IPv6 requests we receive to a selection of dual-stacked properties on Akamai's content, site, and application delivery platform. The hundreds of billions of IPv4 and IPv6 requests analyzed across a 24-hour window represent traffic to a diverse set of customer sites across various industries, geographies, and user populations.

APNIC: APNIC recruits random measurements of IPv6 capability and preference through advertisements placed in web sites worldwide. The advert runs specially crafted HTML5/Javascript and measures a range of properties across wired, wireless and cellular networks. Per-Economy and Per-ASN daily totals are calculated through the RIR delegation stats and daily BGP dumps to map origin-as and economy of registration of each tested clients IP addresses. The measurement has run continuously since 2010 and currently collects around 10 million samples per day. Further information is available here.

Facebook: On June 6th, we examined page loads from randomly selected users. For each user we are able to test if they are using IPv6 to communicate with Facebook. We also know which ISP (World IPv6 Launch participant) they are using at their location. After collecting all data for June 6th, we calculated the percent of unique IPv6 users out of total unique users we saw from each ISP. Many millions of page loads were in our 24-hour data capture for these statistics.

Google: We measure IPv6 adoption among Google users by adding measurement JavaScript to a random sample of visits to various Google properties. The methodology is similar to that described in our paper, Evaluating IPv6 adoption in the Internet. The JavaScript uses HTTP to fetch a URL from an IPv4-only hostname and a URL from a dual-stack hostname, in random order, and then reports the results. The measurement is attributed to the ASN that originates the user's IPv4 address. Measurement endpoints use the same infrastructure that serve regular Google traffic.
