What AAAA does
AAAA records point your domain at IPv6 addresses, the modern successor to IPv4 A records.
Free security tool · no sign-up
AAAA Record Checker.
AAAA records map your domain to IPv6 addresses. Check which addresses are published for your domain.
Free for AwareX client employees and anyone who needs a quick check. No sign-up required.
How to check, verify, and actTry an example:
DNS queried via Cloudflare. We don’t store your input.
Your workplace verification guide
Check it. Verify it. Know what to do next.
Check a hostname's public IPv6 addresses. IPv6 availability is a networking detail, not a security verdict.
Prepare your input
Enter the domain you want to review, such as example.com, without a page path.
Run the check
Select Check records. The tool requests the public DNS records through Cloudflare.
Review the result
Review the AAAA entries with your DNS or email administrator before making changes.
How to verify independently
Enter the exact hostname, such as www.example.com for that service.
Ask IT to compare the IPv6 addresses with the approved host or CDN configuration.
Confirm the result again after any recent hosting or CDN change.
Your next workplace action
Report the exact hostname and returned addresses to IT if there is a connection problem. Do not change DNS or network settings yourself.
What the result means
- IPv6 addresses returned
- The hostname publishes IPv6 addresses. Multiple addresses may be expected.
- No AAAA returned
- The service may use IPv4 only. Missing IPv6 does not automatically mean it is broken or unsafe.
- Unexpected address
- Hosting and CDN addresses can change. Verify with IT before drawing a conclusion.
A returned record is not a security verdict. Missing records can reflect configuration, propagation, or a lookup issue.
Why it matters
Review the addresses. Confirm the host.
AAAA records publish IPv6 addresses for the hostname you enter. Compare them with your hosting provider's configuration; DNS publication does not prove reachability, server ownership, or website safety.
02
Confirm the addresses
Compare published addresses with your hosting provider's expected configuration. An unfamiliar address is a reason to review, not proof of tampering.
03
Know the limit
Remove obsolete entries with your administrator's approval. This lookup does not test connectivity, website safety, or whether a server is still running.
DNS standards · sourced facts
Small record.
Important details.
These IPv6 DNS specification facts explain the returned addresses. They are protocol facts, not a connectivity test or evidence that a website is trustworthy.
128
Bits in an IPv6 address
An AAAA record encodes a 128-bit IPv6 address. It is distinct from an A record, which publishes an IPv4 address.
IETF · RFC 3596, section 2.21
Address per AAAA record
Each AAAA record stores a single IPv6 address. A host with multiple IPv6 addresses uses multiple records.
IETF · RFC 3596, sections 2 and 2.128
The DNS record type
AAAA has DNS type code 28. Requesting that type retrieves published IPv6 records; it does not connect to the listed servers.
IETF · RFC 3596, sections 2.1 and 2.3After the check
Records protect the domain.
People protect the inbox.
AAAA records describe IPv6 addressing, not phishing protection. A published address cannot tell someone whether a link or request is trustworthy. AwareX is a separate human-risk training platform for those decisions.
- Your domain
IPv6 addresses for a hostname
Confirm the addresses with your hosting provider. This check does not visit the website, test IPv6 connectivity, or establish that a destination is safe.
- The attacker
A request still needs scrutiny
Lookalike addresses, compromised accounts, SMS, calls, and deepfakes can reach employees regardless of the records returned by this check.
- AwareX
Your people get practice
Separately, AwareX provides contextual simulations and learning that help teams pause, verify, and report. This lookup does not run or validate those activities.
AwareX is AI-powered human risk testing: it learns your business, runs realistic simulations across email, SMS, voice, QR codes, and deepfakes, and adapts learning to how your people respond.

Five AI agents. One New Age
Human Risk Management platform.
This free tool shows one signal. AwareX is a New Age Human Risk Management platform: five AI agents work together to test your people the way attackers would, and to turn every response into learning.
Context engine
Learns your business from public context: departments, products, and tone, so every test is grounded in how your organization actually works.
Scenario engine
Drafts and scores attack scenarios against your scope, the way a real attacker would plan them.
Lure composer
Writes on-brand emails, messages, and calls with realistic signatures and sender identities, ready for your review.
Risk calibration
Compares predicted risk with how people actually respond, so the picture gets sharper after every wave.
Targeting and routing
Decides who needs practice next and routes learning to the people and teams that need it most.

- See campaign activity and learning progress together.
- Discuss setup, training, and ongoing support.
What this free tool checks
AAAA records map your domain to IPv6 addresses. Check which addresses are published for your domain. This tool queries public DNS through Cloudflare and displays the AAAA records returned for your domain. Use the results to review your configuration; finding a record does not by itself confirm that your domain is secure.

WHY TEAMS PARTNER WITH AWAREX
The benefits of partnering with AwareX
A free check tells you where you stand today. A partnership with AwareX turns that snapshot into a continuous, AI-powered program.
Contextual by default
Simulations are written from your sector, your roles, and current events, so every test feels real to the person receiving it.
Learning in the moment
Every response informs the next test and the lesson that follows it, so training adapts as your risk changes.
Evidence you can present
Dashboards, records, and compliance alignment give leadership and auditors a clear picture of progress.
Support at every step
Setup, campaign planning, and ongoing optimization from a team that runs these programs every day.
Frequently asked questions
Good questions.
Straight answers.
Free access, safe follow-up, and answers specific to this checker.
Yes. Every AwareX free tool is free to use, and you can run as many checks as you need.
No. There is no account, no sign-up, and nothing to install. Open the page, run the check, and read the result.
Share the result with your DNS or email administrator, close any gaps they identify against your provider’s recommended setup, and re-run the check to confirm the change.
An AAAA record maps a hostname to an IPv6 address. It serves a similar role to an A record, which maps a hostname to an IPv4 address.
Only publish one when your hosting service supports IPv6 and provides a working address. A website can still be reachable over IPv4 without an AAAA record.
Multiple addresses can support distributed hosting or redundancy. Compare the returned addresses with your provider’s settings before assuming an unfamiliar address is malicious.
No. This checker reads DNS only. It does not test the server’s availability, routing, firewall, or website response over IPv6.
