The domain is parsed safely
Even when you enter a full URL, the protocol, page path, and query parameters are removed so only the valid host name is queried.

How the check works
Make IPv6 readiness visible and easy to understand
The domain's DNS response is analyzed, valid IPv6 addresses are extracted, and the technical detail is presented as a clear result.
The AAAA DNS record is queried
A secure DNS-over-HTTPS connection is used to look for IPv6 addresses published by the domain.
The result and records are displayed
When records are found, you can view the IPv6 addresses; when none are found, you can review the possible reasons.
An AAAA record is an important signal, not the final test by itself
Publishing an IPv6 address shows that the domain has completed the essential DNS step of an IPv6 deployment. End-to-end reachability also requires correct server, routing, firewall, CDN, and application configuration.
✓Quickly verify public AAAA records.
✓Recheck publication status after DNS changes.
✓Evaluate the result together with server and network reachability tests.
Frequently asked questions
About the IPv6 website check
What does the IPv6 support check test?
The check queries whether a public AAAA record is published in DNS for the domain you enter. An AAAA record maps the domain to an IPv6 address.
Does an AAAA record guarantee complete IPv6 compatibility?
No. An AAAA record is a strong readiness signal, but the server, firewall, CDN, and application configuration must also handle IPv6 traffic correctly.
Can I enter a full URL?
Yes. You can enter a full address beginning with http or https. The tool removes the protocol, path, and query parameters and checks only the domain.
Why might an IPv6 record not be found?
The site may not use IPv6 yet, its AAAA record may not be published, or a recent DNS change may not have propagated to all resolvers.
