Overview
This node retrieves DNS information for a specified domain using the DNS Dumpster API. It is useful for gathering detailed DNS records and related data about a domain, which can help in security assessments, network troubleshooting, or domain research. For example, a user might input "example.com" to obtain DNS records such as A, MX, NS, and TXT entries, helping to analyze the domain's infrastructure or detect potential vulnerabilities.
Properties
| Name | Meaning |
|---|---|
| Target Domain | The domain name for which to retrieve DNS information (e.g., "google.com"). |
| Options | Collection of additional settings: |
| Put Result in Field | The name of the output JSON field where the retrieved DNS data will be stored. Default is "dns". |
Output
The node outputs an array containing one item per input. Each item's json property includes all original input data plus a new field (default named "dns", or as specified by the user) that holds the DNS information retrieved from the DNS Dumpster API. This DNS data is structured as JSON representing various DNS records and related details for the target domain.
No binary data output is produced by this node.
Dependencies
- Requires an active DNS Dumpster API key credential configured in n8n.
- Makes HTTP GET requests to
https://api.dnsdumpster.com/domain/{domain}with appropriate headers including the API key. - The node depends on internet access to reach the external DNS Dumpster service.
Troubleshooting
Common issues:
- Invalid or missing API key: The node will fail to authenticate with the DNS Dumpster API.
- Network connectivity problems: Unable to reach the DNS Dumpster API endpoint.
- Invalid domain format: The API may return errors if the domain parameter is malformed.
Error messages and resolutions:
- Authentication errors typically indicate an incorrect or expired API key. Verify and update the API key credential.
- HTTP request failures suggest network issues or API downtime. Check internet connection and DNS Dumpster service status.
- If no DNS data is returned, confirm the domain exists and is correctly spelled.
