Frequently Asked Questions

What information does the domain intelligence scanner gather?

It performs a comprehensive scan including DNS records (A, AAAA, MX, NS, TXT), SSL certificate details, security headers analysis, email security checks (SPF, DMARC, DKIM), and GeoIP information for the domain's IP address — all in a single scan.

How is GeoIP data obtained?

The tool first resolves the domain to its IP address via DNS, then queries a GeoIP service to determine the server's physical location, ISP, hosting provider, and AS number.

Why might DKIM not be found?

DKIM records are published under specific selectors (e.g. 'default._domainkey.example.com'). The tool tries common selectors like 'default', 'google', 'selector1', and 'selector2', but your domain may use a different selector name that isn't tested.

Is any data stored or logged?

No. All DNS queries go directly from your browser to Cloudflare's DoH resolver. API calls for SSL and headers are proxied through our server but no data is stored or logged.

Can I scan internal or private domains?

No — the tool can only scan publicly accessible domains. Internal domains, localhost, and private IP ranges are not supported as they are not reachable from the internet.

Complete Guide: How to Use the Domain Intelligence Scanner

Get a complete intelligence profile for any domain — WHOIS data, domain age, DNS records, SSL certificate status, security headers, technology stack detection, and more. Our scanner performs a deep recon of any domain in seconds, combining multiple checks into a single comprehensive report.

Step-by-Step Instructions

1
Enter a domain name
Type the domain you want to scan (e.g., example.com). The tool performs a comprehensive multi-faceted analysis.
2
Wait for the scan to complete
The scanner runs 10+ checks in parallel: WHOIS, DNS, SSL, headers, technology detection, and more. Full scan takes 15-45 seconds.
3
Review the intelligence report
See domain age, registrar, nameservers, IP addresses, SSL details, detected technologies, and security header analysis.
4
Export or share
Download the full report or copy individual sections for documentation, presentations, or security assessments.

Common Use Cases

✓Due diligence — investigate domains before business partnerships or acquisitions
✓Competitive research — understand the technology stack and infrastructure of competitors
✓Security assessment — evaluate the security posture of external domains your organization interacts with
✓Domain purchasing — evaluate domain history, age, and current configuration before buying
✓Fraud investigation — gather intelligence on suspicious domains used in phishing or scam operations
✓IT audit — document domain configuration for compliance and governance requirements

Pro Tips

💡Domain age matters for SEO and trust. Older domains generally have more authority. Check WHOIS for registration and expiry dates.

💡Technology detection reveals CMS (WordPress, Shopify), frameworks, analytics, and CDN — useful for competitive intelligence.

💡Missing security headers in the report indicate potential vulnerabilities — use our Security Scanner for a deep security check.

💡Some domains use privacy protection on WHOIS — this is normal and doesn't indicate anything suspicious.
