What this check shows
An AAAA record maps a hostname to an IPv6 address. Clients with working IPv6 connectivity may prefer this route over IPv4, so an incorrect AAAA record can affect only part of your audience.
Comparing AAAA answers globally helps detect stale IPv6 addresses, incomplete dual-stack migrations and resolvers that return no IPv6 data.
When to use it
- Enabling IPv6 for a website or API
- Dual-stack migrations
- Removing an obsolete IPv6 endpoint
- Diagnosing failures that affect IPv6 users only
How to read the result
- A and AAAA records are independent; a correct IPv4 answer does not prove that IPv6 is configured correctly.
- Multiple IPv6 addresses can be intentional for load balancing or redundancy.
- No AAAA answer is valid when a service is deliberately IPv4-only.

Does an AAAA record guarantee IPv6 works?
No. The address must also be routed, reachable and accepted by the destination service and firewall.
Why can a broken AAAA record be disruptive?
Some clients prefer IPv6 and may experience delays or failures even while IPv4 users connect normally.
