What Is an AAAA Record?

An AAAA record is the IPv6 version of an A record - it points a domain to an IPv6 address such as 2606:2800:220:1:248:1893:25c8:1946. This tool lists a domain's AAAA records and their TTL.

When to Use It

To confirm a website is reachable over IPv6 (dual-stack).
When some visitors, often on mobile networks, cannot reach a site that works for others.
After enabling IPv6 at your host or CDN.

How to Use It

Enter the domain.
Check that the listed IPv6 addresses match your server or CDN.

Understanding the Result

No AAAA records means the site is IPv4-only, which still works for nearly everyone. A wrong or outdated AAAA record is worse than none: IPv6-capable visitors will try it first and may fail to connect.

Limitations

The lookup shows what DNS says, not whether the server actually answers on IPv6. See IPv4 records with the A Record Lookup.

Frequently Asked Questions

An AAAA record is the IPv6 equivalent of an A record - it maps a hostname to a 128-bit IPv6 address, rather than the older 32-bit IPv4 addresses that A records use.

Not strictly - IPv4 via an A record alone is still enough to reach every visitor. An AAAA record adds IPv6 connectivity for visitors and networks that prefer or require it, which is a growing share of global internet traffic.

It simply means the domain has no IPv6 address configured - IPv6 support is optional, and the absence of an AAAA record does not affect IPv4 (A record) reachability at all.

IPv6 availability is not a confirmed direct ranking factor, but ensuring your site is reachable across as much of the modern internet as possible is generally good practice for maximizing real user access and site reliability.

Most modern hosting providers and CDNs support IPv6 and can provide or auto-configure an AAAA record - check your specific host's network/IPv6 settings, since this is typically enabled at the infrastructure level, not something you compute yourself.

Yes - IPv6 addresses use eight groups of hexadecimal digits separated by colons (e.g. 2001:0db8:85a3::8a2e:0370:7334), a visually very different format from the familiar dotted-decimal IPv4 style.

No - they're entirely separate, complementary record types serving different address families. A client capable of IPv6 will typically prefer the AAAA record; one that isn't falls back to the A record automatically.
