AAAA Record Lookup
Find IPv6 addresses for any domain
This page provides original, human-reviewed information about AAAA record lookups and IPv6 DNS resolution, including dual-stack behavior and why IPv6 records matter for modern deliverability. The content is written to be clear, accurate, and useful for both people and search systems.
AAAA records (quad-A records) map domain names to IPv6 addresses. They're the IPv6 equivalent of A records, enabling websites and services to be accessible over the newer IPv6 protocol.
Why IPv6 and AAAA Records Matter:
- Address Space:IPv6 provides vastly more addresses than IPv4
- Future-Proofing:IPv6 is the future of internet addressing
- Performance:Can provide better routing and performance
- Security:Built-in security features with IPsec
IPv6 Address Format:
IPv6 addresses are 128-bit addresses written in hexadecimal notation, separated by colons.
Basic AAAA Record Configuration:
IPv6 Address Shortening:
Full Address
Shortened Address
Leading zeros and consecutive zero groups can be omitted
No AAAA Records
Domain not accessible via IPv6
Solution: Add AAAA records if your server supports IPv6
IPv6 Connectivity Issues
Server has AAAA record but IPv6 doesn't work
Solution: Verify server IPv6 configuration and firewall rules
Malformed IPv6 Address
Invalid IPv6 address format in AAAA record
Solution: Verify IPv6 address format and syntax
Do I need AAAA records if I have A records?
AAAAA records are optional but recommended for future-proofing. They enable IPv6 connectivity forusers who have it.
Why are they called AAAA records?
AAAA records are called "quad-A" because IPv6 addresses are four times longer than IPv4 addresses(128-bit vs 32-bit).
Can I use both A and AAAA records?
Yes, this is called "dual-stack" configuration and is recommended. Clients will use IPv6 ifavailable, falling back to IPv4.
