AAAA Record
What this is
The AAAA record maps a domain to an IPv6 address — the modern, much larger address space that runs alongside IPv4. Dual-stack sites publish both A and AAAA records.
How to read your result
Having no AAAA record is common and not an error — it simply means the site is IPv4-only. If an AAAA record exists, confirm the address is actually served by your host, because a broken AAAA record is worse than none.
Common problems and how to fix them
AAAA record points to an address that does not answer
How it shows up: Users on IPv6-capable networks (many mobile carriers) experience slow first connections or intermittent failures, while IPv4 users see nothing wrong.
How to fix it: Either fix the address so the server genuinely answers on IPv6, or remove the AAAA record entirely. Modern browsers fall back to IPv4 (Happy Eyeballs), but not all clients do it gracefully.
Host supports IPv6 but no AAAA record is published
How it shows up: IPv6-only clients cannot reach the site directly; you miss out on the faster path for dual-stack users.
How to fix it: Ask your hosting provider for the server's IPv6 address and publish it as an AAAA record on the same names that carry A records.
