DNS Lookup: Free Online Tool for DNS Queries

DNS Lookup: Free Online Tool for DNS Queries via DoH

DNS Lookup is a universal tool for performing DNS queries via DNS over HTTPS (DoH). The tool allows you to query DNS records through public DoH servers (Cloudflare, Google, Quad9), check SPF/DKIM/DMARC records, compare results between different servers, view TTL and record types.

🔒 Main Advantage: Security and Privacy

  • 100% Privacy: All DNS queries are executed directly from the browser via DoH. No data is sent to our server.
  • Encryption: DNS over HTTPS ensures encryption of all DNS queries
  • Multiple Providers: Compare results between Cloudflare, Google, and Quad9

✨ Key Features

  • DNS over HTTPS (DoH): Execute DNS queries via HTTPS protocol
  • Multiple Record Types: Support for A, AAAA, MX, TXT, CNAME, NS, SOA, PTR records
  • Result Comparison: Compare responses from different DoH providers
  • SPF/DKIM/DMARC Checking: Automatic checking of email security records
  • WHOIS: Get domain registration information
  • Port Check: Check open ports on IP address
  • RBL Check: Check IP address in blacklists
  • DNSSEC: Check DNSSEC signature for domain
  • DNS Trace: Trace DNS queries
  • GeoIP: Determine geographical location by IP address

📋 How to Use

  1. Enter domain or IP: Specify domain (e.g., google.com) or IP address
  2. Select record type: Choose DNS record type (A, AAAA, MX, TXT, etc.)
  3. Select DoH providers: Choose one or more providers (Cloudflare, Google, Quad9)
  4. Click "Lookup": Execute DNS query
  5. View results: Study responses from selected providers

💡 Additional Tools

  • WHOIS: Get domain registration information, including registrar, creation and expiration dates
  • Port Check: Check open ports on IP address (80, 443, 22, 25, 53, and others)
  • RBL Check: Check if IP address is in spam blacklists
  • DNSSEC: Check if domain is signed with DNSSEC
  • DNS Trace: Perform DNS query tracing for domain
  • GeoIP: Determine geographical location of IP address
  • Check All Together: Run all additional tools simultaneously

🔧 Technical Details

  • DoH Providers: Cloudflare (1.1.1.1), Google (8.8.8.8), Quad9 (9.9.9.9)
  • Query Format: JSON over HTTPS according to RFC 8484
  • Record Types: A (1), AAAA (28), MX (15), TXT (16), CNAME (5), NS (2), SOA (6), PTR (12)
  • Security: All queries are encrypted via HTTPS
  • Privacy: No data is stored or logged
