AAAA Record Lookup Tool

What is a DNS AAAA Record?

A **AAAA (quad-A)** record is the IPv6 equivalent of an A record. It maps a domain name to a 128-bit IPv6 address. As the internet gradually transitions from the limited IPv4 address space to the vast IPv6 space, AAAA records are becoming increasingly important for ensuring modern network connectivity.

IPv4 vs. IPv6

A domain can have both A records (for IPv4) and AAAA records (for IPv6) simultaneously. This allows the domain to be accessible from both older IPv4-only networks and modern IPv6-enabled networks.

• A Record (IPv4): Points to a 32-bit address like 93.184.216.34.
• AAAA Record (IPv6): Points to a 128-bit address like 2606:2800:220:1:248:1893:25c8:1946.

When a user on an IPv6-capable network tries to access your site, their browser will typically prefer the AAAA record if one is available, falling back to the A record if not. This ensures a smooth experience for all users, regardless of their network protocol.

AAAA Record Format

The structure of an AAAA record is very similar to an A record:

[Domain Name] [TTL] IN AAAA [IPv6 Address]

• Domain Name: The hostname, such as www.example.com.
• TTL (Time To Live): The caching duration in seconds.
• IN: Stands for Internet.
• AAAA: Specifies that this is an IPv6 Address record.
• IPv6 Address: The 128-bit IP address of the server.

Our tool queries DNS servers to find and display these IPv6 addresses, helping you verify that your domain is correctly configured for the modern internet.
