Map the records behind the name.

A transparent resolver view
Useful evidence, with its limits visible.
DNS is distributed and cached. This page is a point-in-time view from ACA's configured recursive resolver—not a worldwide propagation test.
Absence needs context
An MX or NS gap may need attention. An apex CNAME, IPv6 address or CAA policy can be legitimately absent.
DNSSEC is cautiously worded
Visible DS and DNSKEY records are useful signals. This first release does not claim full chain validation.
You keep the choice
Use the evidence yourself or ask ACA for a one-off domain and DNS review.
