IPv6 Compatibility Test
Check whether a domain is actually reachable over IPv6 — DNS records, nameservers, and live connectivity.
Free to use — no account required.
Domain
Enter a hostname to check its IPv6 readiness — no https:// prefix needed.
What This Test Covers
Every signal that decides whether IPv6 clients can reach a host.
IPv6-Focused Checks
Every check targets IPv6 specifically — AAAA records, IPv6 nameservers, TLD delegation, and glue records — rather than a generic DNS health score.
A Clear Verdict
Compatible, partially compatible, or not compatible, decided by the checks that actually matter: AAAA resolution and end-to-end IPv6 connectivity.
Exportable Results
