IPv6 Deployment Aggregated Status

As of 2017-04-19 and limited to the top-50 per Top Level Domain extracted from defunct Alexa top 1 million web sites (this list has been desactivated end of November 2016) but this site continues to use the 'frozen' state of Alexa. We are working on the Cisco OpenDNS Umbrella list. See the bottom of this page for more information on the tests.

Tests are:

Web:
- GREEN: a AAAA exists for www.$domain or $domain and an HTTP connection over IPv6 was successful
- ORANGE: a AAAA exists for www6.$domain or ipv6.$domain or www.ipv6.$domain and an HTTP connection over IPv6 was successful
- RED: no AAAA exists for any sensible derivation of $domain or an HTTP connection over IPv6 was not succesful
Email:
- GREEN: a AAAA exists for one MX of $domain and a SMTP connection over IPv6 was successful
- ORANGE: a AAAA exists for one MX of $domain but a SMTP connection over IPv6 was not successful
- RED: no AAAA exists for any MX of $domain
DNS:
- GREEN: a AAAA exists for one NS of $domain and a DNS query over IPv6 was answered
- RED: no AAAA exists for any NS of $domain but a DNS query over IPv6 was not answered
- n/m: means n servers out of m have an IPv6 address

OpenDNS rank is n/m meaning n^th in the country (actually TLD -- so not very accurate) and m^th worldwide. Before 20th of November 2016, the world-wide ranking was based on Alexa top 1 million web sites until the service was discontinued by Alexa. Since 20th of December 2016, the source of the top 1 million is Umbrella service by OpenDNS (a Cisco division). The data set are not consistent, so, it may be difficult to compare the situation before and after December 2016.
