Email Security

Analyze Your Email Security Configuration

SPF, DKIM, and DMARC protect your domain from email spoofing and phishing attacks. We check all three.

SPF
Sender Policy Framework defines which IP addresses are allowed to send email on behalf of your domain.
DKIM
DomainKeys Identified Mail adds a cryptographic signature to emails to prove authenticity.
DMARC
Domain-based Message Authentication tells recipients what to do when SPF or DKIM checks fail.
REST API

Integrate DNS Lookups Into Your Workflow

Clean, documented JSON API endpoints. No authentication required for basic usage.

FAQ

Frequently Asked Questions

What is DNS Intelligence Pro?
DNS Intelligence Pro is a professional DNS lookup and domain analysis tool. It lets you query all DNS record types, check WHOIS information, analyze email security configurations (SPF, DKIM, DMARC), verify DNS propagation, and gather domain intelligence — all from one interface.
What DNS record types can I look up?
You can look up all major DNS record types: A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail servers), NS (name servers), TXT (text records), CNAME (aliases), SOA (start of authority), SRV (service records), PTR (reverse DNS), and CAA (certificate authority authorization).
What is email security score?
The email security score rates your domain's email protection from 0–100. It checks for: SPF record (+30 points), DKIM record (+30 points), DMARC record (+30 points), and DNSSEC (+10 points). A score of 90+ is excellent. Scores below 60 indicate missing critical protections.
How does DNS propagation checking work?
DNS propagation happens when you make DNS changes — the new values need time to spread to DNS servers worldwide. Our tool queries 8 major DNS servers (Google, Cloudflare, OpenDNS, Quad9, and others) simultaneously and shows you which ones have your latest DNS values.
Is there a rate limit?
Yes, to ensure fair usage, the tool is limited to 60 lookups per IP per hour for the web interface, and 100 requests per hour for the API. These limits are generous for personal and development use.
Can I use the API in my application?
Yes! The REST API endpoints (/api/dns.php, /api/whois.php, /api/domain.php) are publicly accessible and return JSON. No API key is required for basic usage. Just send a GET request with your domain as a query parameter.
Are lookup results cached?
Yes. DNS records are cached for 5 minutes and WHOIS data for 1 hour. This improves performance for popular domains while ensuring reasonably fresh data. Cache timing matches the typical DNS TTL for most records.
Is this tool free?
Yes, DNS Intelligence Pro is completely free to use with no registration required. The API is also free for reasonable usage within rate limits.
