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 aid 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.

Output
The node outputs an array of items, each containing a json object. Within this json object, there is a field (by default named "dns", or as specified by the user) that holds the DNS information retrieved from the DNS Dumpster API. This data includes various DNS records and related details in JSON format.
No binary data is produced by this node.
Dependencies
- Requires an API key credential for the DNS Dumpster service.
- The node makes HTTP GET requests to
https://api.dnsdumpster.com/domain/{domain}with appropriate headers including the API key. - Users must configure the node with a valid DNS Dumpster API key credential before execution.
Troubleshooting
Common Issues:
- Missing or invalid 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 input: If the domain is malformed or does not exist, the API may return errors or empty results.
Error Messages:
- Authentication errors typically indicate issues with the provided API key; verify the key is correct and has necessary permissions.
- HTTP request failures may suggest network issues or incorrect URL formatting.
Resolutions:
- Ensure the API key credential is correctly set up in n8n.
- Verify internet connectivity and that the DNS Dumpster API endpoint is reachable.
- Double-check the domain name input for correctness.
