IPv6 test

Checks whether a domain has a published AAAA record (IPv6 address). This check is DNS-level only: it does not test real IPv6 connectivity from this server.

Scope of this check

We only verify whether the domain publishes an AAAA record. We do not test real IPv6 connectivity from this server: the absence of AAAA is a reliable signal, but the presence of AAAA does not guarantee every visitor can reach it over IPv6.

Why IPv6 matters

More and more access providers hand out native IPv6. A domain without AAAA still works over IPv4, but loses a direct path for IPv6-only networks.

Frequently asked questions

Quick questions about this tool

Do you test if my site actually responds over IPv6?

No. We only confirm whether the AAAA record is published in the domain's DNS; no real IPv6 connectivity is available on this server.

Do I need IPv6 to work?

It is not mandatory today, but having it improves reach on networks already running over IPv6.
