What is rapiddns?
rapiddns is a technical utility designed for security professionals, DevOps engineers, and developers who need to perform extensive DNS discovery. By interfacing with the RapidDNS API, this tool allows users to uncover subdomains, map IP addresses, and analyze CIDR blocks with high speed and precision. As part of the Openclaw Skills ecosystem, it provides a standardized way to integrate DNS intelligence into automated workflows.
The tool is built to handle massive datasets, offering features like auto-pagination and advanced filtering. Whether you are conducting a security audit or mapping out cloud infrastructure, rapiddns provides the raw data needed to understand a domain's full DNS footprint.
rapiddns Use Cases
- Performing comprehensive subdomain enumeration for bug bounty hunting or security assessments.
- Conducting reverse IP lookups to identify all domains hosted on a specific server.
- Mapping out entire network ranges using CIDR enumeration to find forgotten assets.
- Filtering DNS records by specific types such as MX, CNAME, or AAAA for targeted analysis.
- Exporting bulk DNS data for offline processing and integration into custom reporting tools.
How rapiddns Works
- The user initiates a search query using a domain, IP address, or CIDR range.
- The tool sends a request to the RapidDNS API, utilizing an API key for unrestricted access and export capabilities.
- Results are retrieved and can be filtered using Elasticsearch-style advanced query syntax (e.g., domain:example AND type:A).
- The CLI automatically handles pagination through the --max flag to ensure all relevant records are captured.
- Data is output in the user's preferred format (JSON, CSV, or Text) or piped directly into other command-line utilities.
rapiddns Setup
Option 1: Pre-built Binary
Download the appropriate version for your OS from GitHub and move it to your path:
# Example for Linux
VERSION="1.0.2"
curl -sL "https://github.com/rapiddns/rapiddns-cli/releases/download/v${VERSION}/rapiddns_v${VERSION}_linux_amd64.tar.gz" | tar xz
sudo mv rapiddns /usr/local/bin/rapiddns-cli
Option 2: Go Install
Requires Go 1.24+:
go install github.com/rapiddns/rapiddns-cli@latest
Configuration
To unlock full features and bulk exports, configure your API key from rapiddns.io:
rapiddns-cli config set-key <YOUR_API_KEY>
rapiddns Data Schema & Taxonomy
The tool provides structured output with the following data points:
| Field | Description |
|---|---|
| subdomain | The full subdomain string (e.g., mail.example.com) |
| type | The DNS record type (A, AAAA, MX, CNAME, TXT, etc.) |
| value | The value associated with the record (IP address or target) |
| timestamp | The Unix timestamp of the last observation |
| date | A human-readable date of the last observation |
When using the export feature, results are stored in a local result/ directory, organized by query type.
rapiddns Advanced Features
- Advanced Elasticsearch-style query syntax for complex boolean filtering of DNS records.
- Automatic entity extraction to generate deduplicated lists of subdomains or IP addresses.
- Seamless pipe integration with --silent mode and text output for multi-tool security pipelines.
- Bulk export workflow including automated task triggering, polling, and downloading of large datasets.
- CIDR range enumeration for discovering assets across entire network subnets.
