What is an AAAA record?

An AAAA record maps a domain name to an IPv6 address, the 128-bit successor to IPv4. It is the IPv6 counterpart of the A record and lets IPv6-capable clients reach your server.

How do I use this tool?

Enter a domain name and run the lookup; our server queries the domain's AAAA records live and lists every IPv6 address it returns. If the result is empty, the domain simply has no AAAA record and is reachable only over IPv4.

Why do AAAA records matter?

They enable your site to be served over IPv6, which is required for clients on IPv6-only networks and can improve reachability as IPv4 addresses grow scarce. Modern browsers prefer IPv6 when an AAAA record is present.

How do I read the result?

Each row is a colon-separated IPv6 address (for example 2606:4700:4700::1111) that your domain resolves to. Multiple addresses mean traffic can be balanced across several IPv6 endpoints.

Why does my domain have an A record but no AAAA record?

That is normal and only means the domain is not published on IPv6, so it works fine over IPv4. To add IPv6, create an AAAA record at your DNS host pointing to your server's IPv6 address once it has one.

Blacklist Look Up

Looks up whether this domain's IP address (or the IP address you entered) appears on common email blacklists (DNSBL) — being listed can cause outgoing mail to be rejected or sent to spam.

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.
