NewB: Read the primer, be able to answer some quick and easy questions.
Explorer: Verify that you can access an IPv6 website (ours!)
Enthusiast: Verify that you have an IPv6 capable web server that we can connect to and fetch information from. This should be entered as a FQDN and not an IPv6 address.
Administrator: Verify that you have a working IPv6 capable MTA by sending you an email only over IPv6.
Professional: Verify that your MTA has working reverse DNS (ex: dig mx $domain +short ; dig aaaa $mx +short ; dig -x $mxAAAA +short)
Guru: Verify that the authoritative NS for your domain have AAAA records, and respond to queries for the domain (ex: step 1 is dig ns $domain ; dig aaaa $ns | step 2 is dig aaaa $domain @$nsAAAA)
Sage: Check to see if your domain's authoritative NS have IPv6 glue with their listed TLD servers. Meaning the TLD server can directly answer for the host record (ex: dig +trace ns $domain to get the TLD server list then dig aaaa $ns @TLD for the glue).
