About this tool. AAAA records are the IPv6 version of A records. More networks are IPv6-only every year, so having AAAA records makes your site reachable for everyone and can slightly improve performance on modern networks.
How to read your aaaa record lookup results
An AAAA record maps a hostname to an IPv6 address. Not every domain has one yet, and that is normal.
If both A and AAAA exist, clients on IPv6 networks will usually prefer the AAAA.
Common problems and how to fix them
IPv6 users report problems but IPv4 users do not
A broken or stale AAAA record can black-hole IPv6 traffic. Verify it points to a server that actually answers on IPv6, or remove it.
Common questions.What is an AAAA record?
The IPv6 version of an A record. It maps a hostname to a 128-bit IPv6 address.
Do I need an AAAA record?
Not required, but it lets IPv6-only clients reach you directly. Only publish one if the server truly answers on IPv6.
