Japan is scanned since 2010-06-17 and the last information is dated 2025-10-25. It is based on the Alexa top-1-million list of web sites; please note that end of November 2016, this list was no more updated, so, the site ranking is 'frozen' since November 2016. Return to Aggregated Results. Jump to the IPv6 allocated prefixes.
Leave the cursor over a green/orange box to have more information (MSS, MTU). Hoover the mouse over a red box to display the AS of the web site (this is usually a good indication of the web hoster).
Click on any graphs or maps to zoom on it.
You can add a widget on your own web site with your country IPv6 status or get more geographical maps, click here to see how ;-)
: this site participated at the World IPv6 Day in 2011.
: this site has removed the IPv6 access after the World IPv6 Day (fear?).
