What are AAAA records?

AAAA records, also known as IPv6 address records, are a type of DNS (Domain Name System) record used to map a domain name to an IPv6 address. Just like A records, which map domain names to IPv4 addresses, AAAA records provide the translation from human-readable domain names to machine-readable IPv6 addresses.

IPv6 addresses are longer than IPv4 addresses and are represented as eight groups of four hexadecimal digits, separated by colons. For example, an IPv6 address might look like this:


AAAA records are used to specify the IPv6 addresses associated with a domain or subdomain. They play a crucial role in ensuring that devices and services on IPv6-enabled networks can communicate with each other over the Internet.

Here's an example of an AAAA record in a DNS zone file:

example.com.   IN   AAAA   2001:0db8:85a3:0000:0000:8a2e:0370:7334

In this example:

  • example.com. is the domain name.
  • IN indicates the Internet class.
  • AAAA specifies the record type.
  • 2001:0db8:85a3:0000:0000:8a2e:0370:7334 is the IPv6 address associated with the domain.

AAAA records are essential for the proper functioning of IPv6 networks and are used to enable connectivity and communication between devices, servers, and services using IPv6 addresses. They are managed through DNS hosting providers or domain registrars and are typically used alongside other DNS records to configure a domain's settings.
