DNS Lookup

Perform live DNS queries using public DNS-over-HTTPS resolvers. Look up A, AAAA, MX, TXT, NS, CNAME, SOA, and other record types.

What It Does

The DNS Lookup tool queries live DNS records for any domain using public DNS-over-HTTPS (DoH) resolvers. It supports 10 record types and can query all common types in parallel with a single click. Results are displayed in a clean table with TTL values and can be exported in zone-file-style format.

How to Use It

  1. Navigate to DNS Tools → DNS Lookup from the top menu.
  2. Enter a domain name (e.g., example.com) in the Domain Name field.
  3. Select a Record Type from the dropdown (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, PTR).
  4. Choose a Resolver (Google, Cloudflare, or Quad9).
  5. Click Lookup or press Enter.
  6. View the results table showing each record's name, type, TTL, and value.
  7. Use Copy All or Download .txt to export in zone-file format.

All Records Query

Click the All Records quick button to query A, AAAA, MX, TXT, NS, CNAME, SOA, and CAA records simultaneously. Results are grouped by record type. This gives you a complete DNS profile for any domain in one click.

Choosing a Resolver

  • Google (8.8.8.8): Widely used, fast, good global coverage.
  • Cloudflare (1.1.1.1): Privacy-focused, often the fastest resolver.
  • Quad9 (9.9.9.9): Security-focused, blocks known malicious domains.

Comparing results across resolvers can help identify propagation delays or resolver-specific filtering.

Example: Checking Email Configuration

You want to verify that a domain's email is properly configured:

  1. Enter the domain name.
  2. Click MX to see mail server records and priorities.
  3. Click TXT to check for SPF, DKIM, and DMARC records.
  4. Or click All Records to see everything at once.

Privacy

DNS queries are routed through a server-side proxy to avoid browser CORS restrictions. The proxy does not log queries, domains, or IP addresses. Your search history is never stored.

Use Cases

  • DNS troubleshooting: Verify records resolve correctly after changes.
  • Propagation checks: Compare results across resolvers to spot delays.
  • Email diagnostics: Check MX, SPF, DKIM, and DMARC records.
  • Security audits: Review CAA records and unexpected CNAME chains.
  • Documentation: Export DNS records for migration planning.
