AAAA Record Lookup

whatsmydns.net AAAA Record Lookup tool lets you query DNS servers and get instant results.

IPv6, Quad A, or AAAA records lookups are used to determine the AAAA records associated with a domain.

DNS AAAA Record

AAAA records, or Address v6 records are used to store IP address information for a domain name.

AAAA records can only store IPv6 IP addresses (e.g. fe80::1). In order to store IPv4 addresses, an A record must be used.

Many websites and servers often do not provide any AAAA records as they do not yet support the newer IPv6 protocol and only have A records.

Most websites that support IPv6 only need to have a single AAAA record for a given identifier, however it is possible to provide multiple AAAA records.

AAAA addresses can be represented in either a fully uncompressed format or in their short notation. You can easily convert between these formats using the IPv6 Expander or IPv6 Shortener tools.

While AAAA records are for pointing domain names into IP addresses, if you need to point an IP address into a domain name then a PTR record should be used. The reverse DNS lookup tool can check all your forward and reverse DNS records to ensure they are configured correctly.

There are also tools which can convert IPv6 to IPv4, or convert IPv4 to IPv6.

Example AAAA record

An example AAAA record may look like the following:

www represents identifier of the record. To set the value for the root of the domain you must use @.

AAAA is the record type.

fe80::1 is the value of the record. This must be an IPv6 address.

3600 is the TTL (time to live) of the record in seconds, this example represents 1 hour. This means that when a record has had updates made to it, then it will take 1 hour to update.

Multiple AAAA records

When multiple AAAA records are associated with the same domain record, one is used at random - this can be useful for larger websites or services as a technique to load balance IPv6 traffic across multiple servers where a single server or network device cannot handle the traffic alone.
