When the domain's own DNS is broken (its name servers unreachable or its DNSSEC failing) it answers with the resolver's Extended DNS Error instead of failing. For TXT or ALL on a name that exists it grades the domain's email security A-F: SPF (lookups counted through nested includes against the limit of 10, and issues), DMARC strength (inherited from the parent domain when a subdomain has none), MTA-STS, TLS-RPT and BIMI. Takes Unicode names and IP addresses (reverse lookup); special-use names such as localhost or .local are a free 400. Use when debugging a domain, auditing email setup or spoofing protection, or verifying where a site points.
