HOW IT WORKS
About the Website IPv6 Connectivity Test
The test retrieves AAAA records and uses IPv6-specific tools when installed. A service is not fully dual-stack merely because an AAAA record exists; routing, firewall and application listeners must also work.
How to use this result
- Run the test from this server.Use a public hostname, address, prefix or ASN in the format requested above.
- Compare test locations.Choose another available 39D node or run a local command to identify location-specific behaviour.
- Correlate related evidence.Use the related tools below to compare DNS, routes, ports, TLS and application responses.
- Keep the time and context.Routing, DNS caches and reputation data change, so record when the result was collected.
Common interpretation issues
- Publishing an unreachable AAAA record can cause delays or failures for IPv6-capable clients.
- Some hosting platforms have IPv6 DNS but no matching firewall rule.
- Happy Eyeballs in browsers can hide partial IPv6 failures.

Frequently asked questions
Can this test my own broadband IPv6?
No. Use the Do I Have IPv6? browser test for your own connection.
Should IPv4 and IPv6 serve the same content?
Usually yes, unless the service has a deliberate protocol-specific design.
