Command Syntax
curl accept:application/dns-json https://cloudflare-dns.com/dns-query?name=example.com&type=A
What It Does
Tests encrypted DNS resolver endpoints over HTTPS APIs.
When to Use It
Use when validating privacy-path behavior or comparing DoH vs classic resolver outcomes.
Example Output
JSON or wire-format replies include status, question, and answer objects.
How to Interpret Results
Compare content and TTL with UDP/TCP answers to spot policy or cache divergence.
How DNS Panopticon Detects This
- Relevant checks: Delegation integrity, resolver consistency, DNSSEC health, and suspicious record-pattern checks.
- Severity mapping: Informational, medium/high, or critical based on exploitability and user impact.
- Score impact: Reliability and security scoring dimensions are reduced according to blast radius.
- Related findings users will see: NS drift, validation failure, orphaned CNAMEs, wildcard exposure, and policy misconfiguration alerts.
Operator Checklist
- Verify behavior from at least two public resolvers and one resolver inside your own network before making changes.
- Make one change at a time, capture before/after query output, and wait for TTL windows to clear so you can confirm impact.
- Document the root cause and the final fix in your runbook to shorten future incidents.
