what is aaaa record in dns

AAAA record in DNS is a record that maps a domain name to an IPv6 address. It’s the IPv6 counterpart to an A record , which maps to IPv4.

Quick Scoop

If someone types your domain into a browser, DNS can use the AAAA record to find the server’s IPv6 address and connect to it. If both A and AAAA records exist, devices typically use whichever IP version they support.

In plain English

• A record = domain → IPv4 address.

• AAAA record = domain → IPv6 address.

• “AAAA” is often called “quad A”.

Example

For example.com, an AAAA record might point to something like: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Why it matters

AAAA records are used when a site or service supports IPv6 , which is the newer internet address format. They help devices reach servers over IPv6 without needing IPv4.
