Domain Health Inspector

Audit DNS and registration controls, then compare Cloudflare and Google resolver answers for propagation and DNSSEC differences.

DNS / MAIL / DELEGATION

Inspect a domain

Read-only · public data

The inspector compares Cloudflare and Google DNS-over-HTTPS answers, requests Google results without client-subnet localization, and discovers registration data through RDAP. It never connects to the inspected domain or scans ports. One-time inspection results are not stored; when you explicitly start a watch, its public DNS observations are retained for up to eight days and then automatically removed. “Advisory” means optional hardening, not a broken configuration. Findings reference RFC 2182, RFC 4035, RFC 7208, RFC 9989, and related standards.
