DNS Examiner
AI-powered zone analysis that checks your DNS configuration for issues across email, security, web, and nameserver delegation — then gives you specific fixes.
Included in every plan
DNS Examiner is available on all Edge DNS plans at no extra cost. Run examinations as often as you need.
How to Use
- 1 Open a DNS zone and navigate to the Examiner tab
- 2 Click Run Examination — the analysis takes up to 30 seconds
- 3 Review your health score, issues, and recommendations. Fix issues directly in the Records tab.
What It Checks
Email Deliverability
Validates SPF, DKIM, and DMARC records. Checks MX configuration and flags missing or misconfigured email authentication.
Security
Reviews CAA records, checks for overly permissive wildcards, and verifies security-related DNS configuration.
Web Accessibility
Confirms A/AAAA records resolve, checks for CNAME-at-apex conflicts, and verifies www subdomain setup.
Nameserver Delegation
Compares live NS lookups against your assigned Edge nameservers. Identifies delegation mismatches at your registrar.
Best Practices
Audits TTL values, flags duplicate or conflicting records, checks MX priority spread, and identifies orphaned entries.
Health Score
Each examination produces a health score from 0 to 100 based on the severity and number of issues found.
| Score | Rating | Meaning |
|---|---|---|
| 80–100 | Good health | No critical issues. Minor improvements may be suggested. |
| 60–79 | Needs attention | Some warnings that should be addressed. |
| 0–59 | Issues found | Critical issues that may affect email delivery, security, or availability. |
Issue Severity
Issues are categorised by severity to help you prioritise fixes.
Critical
Issues that directly impact functionality — missing SPF causing email rejection, nameserver delegation mismatch, etc.
Warning
Potential problems that may cause issues — missing DMARC policy, no CAA record, suboptimal TTLs.
Info
Suggestions for improvement — adding a www CNAME, optimising TTL values, etc.

Examination results are saved automatically. When you return to the Examiner tab, your most recent result is displayed with the date and time it was run. Click Re-run at any time to get a fresh analysis.
