Quick Start

  1. Visit the DNS Lookup tool on HeronTool.
  2. Enter a domain name, e.g., example.com, in the input field.
  3. Select the record type (A, AAAA, MX, TXT, etc.); A is default.
  4. Click "Query". The tool sends an HTTPS-encrypted request (DoH) to public DNS servers and displays the results.

Advanced Usage

  • Batch Lookup: Paste multiple domains (one per line) to get records for each in sequence.
  • Custom DNS Server: Choose Google, Cloudflare, or a custom DoH endpoint from the dropdown to compare resolutions.
  • Export Results: Click "Export JSON" to save structured data for scripting or analysis.

FAQ

Q: What's the difference between DoH and normal DNS?
A: DoH wraps DNS queries in HTTPS, preventing eavesdropping or tampering. HeronTool's DNS lookup uses DoH by default—no extra setup needed.

Q: Why is the result empty?
A: The domain may not exist, the record type is wrong, or the server hasn't cached it. Check spelling, try another server, or retry later.

Q: Does it support DNSSEC validation?
A: Currently, the tool returns raw records without DNSSEC validation. For validation, use a specialized resolver.
