DNS Lookup
Query public DNS records for a domain and explain what is present or missing.
Run the check
Enter a public target. Checks are a point-in-time sample; private and internal addresses are blocked.
Why it matters
DNS records control where websites, email and verification services point.
Plain-English examples
- A record for example.com
- MX records for a business domain
Recommended fixes
- Keep old records only where still needed
- Use CAA records to limit certificate issuers
- Check MX and SPF together for email changes
Understanding the result
Use findings as a starting point, confirm the intended configuration with your provider, and retest after a change. A successful check does not guarantee security, delivery, uptime or search rankings. Results depend on public DNS and what the server exposes at the time of the check.
