This page is updated daily by a script. The data below was acquired starting at Mon May 29 13:06:01 2017 UTC.

This page shows the IPv6 capability status for the top 500 websites according to MOZ.COM.

The data is gathered by first screen-scraping the 500 web sites from MOZ.COM . The site names are then checked for AAAA records via the raw name and also www.. For sites which have an AAAA record, a further test is done to see if a web server answers at that name using LWP from an IPv6 source address.

Each column is tallied and totals (and percentages) are shown at the bottom of the table.

This site used to use the Alexa 500, but after Alexa was acquired by Amazon, Amazon placed Alexa beyond 50 behind a paywall with a price for each URL retrieved. This page is generated daily and the price for 500 URLs was $125. I wasn't willing to pay $125/day to maintain the list, so I now use the free data from moz.com.

Unfortunately, the moz.com list is semi-static because automated retrieval from openssl or LWP is not possible using the versions of those tools currently installed. As a result, I've downloaded the CSV version from their site once and will try to remember to update it periodically. I apologize for any inconvenience. If anyone has an Alexa/AWS contact that might be friendly to continuing this project without requiring a $125/day investment, please contact me.
