The overall map presents two IPv6 metrics: the overall deployment ratio and the relative deployment index. The former is an average of other metrics and is used to measure the deployment of IPv6 in a scale between 0% (no IPv6 at all) and 100% (everything is IPv6). The purpose of the latter is to compare countries to the currently most advanced IPv6 deployment (which country is graded 10). The color on the world map is based on this index
The overall IPv6 deployment ratio depends on three metrics: IPv6-enabled transit AS, IPv6 content and IPv6 users. How these ratios are computed is described in the sections below. The readiness of the country's infrastructure is described by the ratio of IPv6-enabled transit AS and amounts to 25%. The last 75% of the final ratio are allocated to the geometric mean between the content and the users. Considering that the product of users and content available to these users gives a simple estimation of the actual IPv6 traffic in the country, a geometric mean between content and user ratios is more meaningful than an arithmetic one. A much greater weight of 3 against 1 is explained by the fact that transit AS ratio only represents infrastructures whereas everything else needs to be " working for user traffic to exist.
The relative index uses the same arithmetic mean but with each term divided by their maximum value around the world. This mean may be used to compare several countries and is normalized afterwards from 0 to 10. In this way the best IPv6 country gets an index of 10 out of 10 and countries with very few IPv6 transit AS and users get low index values.

To measure the level of IPv6 readiness of the core of the internet, from a local and global point of view, one good way is to analyze the BGP routing table and measure the IPv6 enablement of Transit ASs.
A Transit AS
is an AS through which packets travel and which is neither the
departure nor the destination.
From a more pragmatic point
of view: all AS that appear on an AS path of BGP table (and that
are not the origin AS or the destination) are considered Transit
AS
More precisely
It is calculated as follows:

The next step is to enable content on a web server. Alexa ranks websites by
pageviews and unique users per country. It is therefore possible
to retrieve the Top 500 websites / country.
For each of
those websites, an AAAA
request is made to DNS
servers for the exact domain name and also possible test names
such as www6.mydomain.mytld or ipv6.mydomain.mytld.
For
each AAAA record test if the webpage is working in IPv6.
