Frequently Asked Questions

DNS Intelligence is a comprehensive DNS lookup and security analysis tool that performs multi-record DNS queries, global propagation checks, reverse DNS lookups, SSL/TLS certificate inspection, and advanced email security analysis - all in one automated workflow.

Unlike basic DNS lookup tools, we provide enriched data including SPF/DMARC/DKIM parsing, MX provider detection, security scoring, and actionable recommendations.

Yes! The web interface at lookup.echovalue.dev is completely free to use for individual domain lookups with all features enabled.

For bulk processing and API access, we offer a pay-per-use model through our API integration.

We support all major DNS record types including A, AAAA, MX, CNAME, TXT (SPF, DKIM), NS, PTR, SOA, CAA, and SRV.

DNS Intelligence is designed for cybersecurity professionals, web developers, IT administrators, and digital marketers needing comprehensive domain analysis and security assessments.

DNS Enrichment is our intelligent analysis layer that goes beyond basic lookups. It automatically identifies email providers (like Google Workspace or Microsoft 365), performs deep email security analysis (SPF/DMARC/DKIM parsing and scoring), categorizes TTL values, and provides actionable security recommendations.

We fetch and analyze live certificate metadata for domains serving HTTPS traffic. This includes the certificate issuer, validity dates, days until expiry (with warnings), TLS protocol versions, and detection of self-signed certificates.

We query your domain across multiple global DNS resolvers (Google, Cloudflare, OpenDNS, Quad9) to verify that your DNS changes have propagated correctly worldwide, identifying any consistency issues.

Reverse DNS Lookup (PTR) resolves IP addresses back to their associated hostnames. This is essential for network reconnaissance, verifying email server authenticity, and identifying server owners.

Yes! You can easily export the complete analysis including all records and enrichment data. Options include copying the JSON directly to your clipboard or downloading it as a file.

We prioritize your privacy. Your search history is stored only in your browser's local storage and is never synced to our servers. We do not use cookies or tracking scripts.

DNS lookups are standard read-only operations. We handle minimal data only for processing queries and bot protection (Cloudflare Turnstile), and we never share data with third parties.

To ensure accurate results, our system automatically strips protocols (http/https), paths, and spaces from your input. For example, entering "https://example.com/page" will be automatically cleaned to query "example.com".

Yes! We fully support Internationalized Domain Names (IDN) containing Unicode characters (e.g., münchen.de, 中国.cn). Our system automatically handles the necessary conversions.

Analysis time depends on enabled options:

• Basic DNS Lookup: 1-5 seconds
• With DNS Enrichment: 10-60 seconds (comprehensive email security analysis)
• With SSL Inspection: +5-15 seconds (certificate fetching)
• With Propagation Check: +10-30 seconds (multiple server queries)

The loading messages will keep you informed of progress. If analysis exceeds 60 seconds, try disabling some advanced options.

Cloudflare Turnstile is our bot protection. If it won't load:

• Ensure JavaScript is enabled in your browser
• Check that Cloudflare domains aren't blocked by ad blockers
• Try disabling browser extensions temporarily
• Clear your browser cache and reload the page
• Try a different browser or incognito mode

Not all domains have all record types. Common scenarios:

• No MX Records: Domain doesn't handle email
• No AAAA Records: Domain doesn't support IPv6
• No TXT Records: No SPF, DKIM, or verification records configured

Make sure you've selected the record types you want to query in Advanced Options. By default, we query A, AAAA, MX, CNAME, TXT, and NS records.

Yes, we offer a robust API for programmatic access, enabling bulk domain processing, CI/CD integration, and automated infrastructure monitoring. It supports all our advanced features with JSON output.

Yes. You can use the DNS tool as an MCP endpoint via Apify for agent workflows and automation. Open the MCP tool here: mcp.apify.com/?tools=njoylab/apify-dns.
