About AAAA records

An AAAA record maps a domain to an IPv6 address, the modern successor to IPv4. Domains may publish AAAA records alongside A records to support IPv6-capable clients.

This lookup queries your AAAA (IPv6 address) records in real time over DNS-over-HTTPS, so you see exactly what resolvers see right now — useful for verifying changes, auditing a setup, or troubleshooting.

FREQUENTLY ASKED QUESTIONS

Got Questions? We Have Answers.

What is an AAAA record?

An AAAA record maps a domain to an IPv6 address, the modern successor to IPv4. It lets IPv6-capable clients reach your server.

Does my domain need an AAAA record?

It is optional but recommended. Publishing AAAA alongside A records makes your site reachable over IPv6 as adoption grows.

Why is my AAAA lookup empty?

Many domains are IPv4-only and publish no AAAA records. An empty result simply means IPv6 is not configured.

Can a domain have both A and AAAA records?

Yes. A dual-stack setup publishes both so clients use IPv6 where available and fall back to IPv4.

Is this lookup live?

Yes. AAAA records are resolved in real time over DNS-over-HTTPS.

What is the TTL?

TTL is the cache lifetime in seconds. Lower TTLs let AAAA changes propagate more quickly.
