IPv6 addresses for nameservers
 

This test checks that the nameservers for your domain have IPv6 addresses.

A full pass requires at least two IPv6 nameservers. A single nameserver will result in a warning.

Nameserver IPv6 connectivity
 

This check sends a test DNS query to to each of the IPv6 addresses obtained in the first test to confirm that the nameservers are listening on the listed addresses

This test is skipped if no addresses are found in the first test.

IPv6 address(es) for web server(s)
 

Attempts to obtain an IPv6 address for www.yourdomain. This test will be skipped if no IPv4 addresses are found for that hostname.

IPv6 address(es) for bare domain name
 

Attempts to obtain an IPv6 address for the specified domain. This is used when users access your website without adding a "www" prefix.

This test will be skipped if there is no IPv4 addresses are found for that hostname.

Web server IPv6 connectivity
 

Establishes a connection to your webserver on the IPv6 addresses found in the "IPv6 addresses for web servers test"

This test will be skipped if no IPv6 addresses were found

Secure web server IPv6 connectivity
 

Establishes a connection to your webserver on the IPv6 addresses found in the "IPv6 addresses for web servers test"

This test will be skipped if no IPv6 addresses were found, or if your servers do not provide SSL connectivity on IPv4.

IPv6 addresses for incoming mail servers
 

Checks that the mail servers listed in your MX records have IPv6 addresses.

This test will pass if at least one of the listed MX servers has an IPv6 address.

Mail server IPv6 connectivity
 

Checks that the mail servers found in the previous test are accepting SMTP connections on their IPv6 address.

This test waits for the remote server to display an SMTP banner. Some mail servers use a delay before displaying such a banner which can slow this test down, or in some cases cause it to time out.

Reverse DNS for mail server IPv6 addresses
 

Checks that any IPv6 addresses found for your incoming mail servers have working reverse DNS for those addresses.

Missing reverse DNS is only classed as a warning as reverse DNS is of more importance for outgoing servers, but there is no reliable way to automatically find the outgoing servers used for a particular domain.

SPF records refer to hosts with IPv6 addresses
 

Checks that any SPF records for your domain have appropriate IPv6 counterparts. Specifically, any MX records referenced must include at least one server with an IPv6 address, and if any explicit IPv4 ranges are included, then there must be at least one IPv6 range included too.

If your domain does not provide any SPF records, this test will pass.

IPv6 nameserver delegation and glue trace (experimental)
 

Checks that all of the zones in the delegation chain between the root nameservers and your zone have working IPv6 for their nameservers, and sufficient glue to find them.

For a full pass, there must be at least two working IPv6 servers at each step in the chain.

If at any step IPv6 addresses for fewer than two nameservers are provided by glue, then the check will result in a warning unless all listed nameservers have IPv6 addresses. This is because otherwise, a resolver may waste time attempting to resolve nameservers that don't have IPv6 addresses.
