AAAA Record Lookup
Find the IPv6 address for any domain name instantly. Check if a website supports modern internet routing.
What is an AAAA Record?
An AAAA record (pronounced "quad-A") is a DNS record that points a domain name to an IPv6 address.
When you type a website name into your browser, the browser asks the DNS system for directions. If the website uses the modern IPv6 system, the DNS will return an AAAA record containing the exact server address so your browser can connect.
Why Do We Need IPv6?
We simply ran out of space in the old system.
The Old System (IPv4)
The original internet address system is called IPv4. It uses A records. It only had enough room for about 4.3 billion unique addresses. Because everyone now has smartphones, smart TVs, and computers, we completely ran out of these addresses years ago.
The New System (IPv6)
IPv6 is the upgrade. It uses AAAA records. The IPv6 system is so massive that it can provide trillions of trillions of unique addresses. It ensures that every device in the future can connect to the internet.
Curious about the switch? You can track global IPv6 adoption on the Google IPv6 Statistics page.
What Does an IPv6 Address Look Like?
Old IPv4 addresses are short and use numbers separated by dots (like 192.168.1.1).
Because IPv6 addresses are so much larger, they use eight groups of numbers and letters (hexadecimal) separated by colons. If an address has a long section of zeroes, they can be replaced with a double colon (::) to make the address shorter to read.

Frequently Asked Questions
What is an AAAA record?
An AAAA record (pronounced quad-A) is a DNS record that points a domain name to an IPv6 address. It does the exact same job as an A record, but uses the newer IPv6 format instead of the older IPv4 format.
Why is it called an AAAA record?
An older IPv4 address (used in A records) is 32 bits long. A new IPv6 address is 128 bits long, which is exactly four times larger. Therefore, the record name is four 'A's (AAAA).
Why does a domain say 'No Records Found'?
Not all websites support IPv6 yet. If a website only uses the older IPv4 system, it will only have an A record, and the AAAA lookup will return no results. This is still very common on the internet today.
Can a domain have both A and AAAA records?
Yes! Most modern websites have both. This is called 'dual-stack' support. It allows older devices on older networks to connect using IPv4, while newer devices connect using the faster, newer IPv6 system.
Do I need an AAAA record for my website?
It is highly recommended, but not strictly required. Setting up an AAAA record ensures your website is future-proof and can be accessed by users who are on IPv6-only internet connections, such as modern cellular networks.
