What is an AAAA Record?

An AAAA record type is a foundational DNS record when IPv6 addresses are used. AAAA records are assigned the IPv6 address for a destination which makes communication between the source and destination possible.

What is an AAAA Record?

An AAAA record (sometimes referred to as a quad A) record gives the IPv6 (Internet Protocol version 6) information when a DNS query is performed. The A in this case stands for Address, similar to A records which resolve a domain namef or an IPv4 address.

Due to scarcity companies are running out of IPv4 addresses and therefore are starting to use IPv6 addresses. The reason there are four As (AAAA) is to reflect that an IPv6 address, which is 128 bits, is four times the size of an IPv4 record, which is 32 bits.

The AAAA DNS record is stored in a DNS zone on a DNS authoritative server usually residing on a company’s network or at a website host company.

What is an AAAA Record Example

We can find an AAAA record by using the DIG command or the nslookup command.

If we take a look at as an example we can see an IPv6 address of 2607:f8b0:4009:80a::200e when we run an nslookup to find the AAAA record for
