Quick Start
- Visit the DNS Lookup tool on HeronTool.
- Enter a domain name, e.g.,
example.com, in the input field. - Select the record type (A, AAAA, MX, TXT, etc.); A is default.
- 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.
