DNS-03 / DNS RECORDS

A / AAAA Lookup

Look up IPv4 (A) and IPv6 (AAAA) address records for any domain.

About the A / AAAA Lookup

A and AAAA records map your domain to IP addresses — A for IPv4, AAAA for IPv6. They're what turn a hostname into an actual server your visitors can reach. This tool looks up both record types for any domain in a single check.

What this tool checks

It resolves both the A (IPv4) and AAAA (IPv6) records for your domain and lists every address returned, so you can confirm your domain points where it should.

IPv4 vs IPv6

A records return IPv4 addresses like 93.184.216.34. AAAA records return IPv6 addresses. Not every domain publishes AAAA records yet, so an empty IPv6 result is common and usually not a problem.

Frequently asked questions

What is the difference between an A and AAAA record?

An A record maps a hostname to an IPv4 address; an AAAA record maps it to an IPv6 address. Both serve the same purpose for their respective IP versions.

Do I need an AAAA record?

It's optional but increasingly recommended. AAAA records let IPv6-only clients reach your site directly. If your host supports IPv6, publishing an AAAA record improves reach and future-proofs your setup.

Why does my domain resolve to multiple IPs?

Multiple A records are used for load balancing and redundancy. DNS returns all of them and clients pick one, spreading traffic across servers or CDN edges.
