About IPv6 test
What does the IPv6 test do?
The IPv6 test checks whether a URL is reachable via IPv6. It checks whether an AAAA record exists and then it also checks whether the web server actually responds to HTTP(S) requests via IPv6.
This tool can come in handy to confirm if IPv6 is set up correctly for your website.
