history
Project history and usage
DNSGen is a DNS name permutation CLI for security researchers and penetration testers doing subdomain discovery and reconnaissance.
Project history
The official README presents DNSGen 2.0 as an advanced DNS name permutation engine. It generates domain-name variations using insertion, number manipulation, affixing, cloud-provider, region, microservice, internal-tooling, and port-prefix patterns.
The project credits Aleph Null s.r.o. for the original concept and names altdns and massdns as related inspiration or workflow neighbors.
Adoption history
DNSGen's adoption is centered on offensive-security and OSINT workflows. The repository is the main upstream surface, while the input metadata shows Homebrew packaging for workstation installation.
How it is used
Typical usage is to feed DNSGen known domains or hostnames, optionally add a custom wordlist, and pipe generated candidates into massdns or another resolver to find live subdomains.
Why package nerds care
DNSGen matters as a small composable recon package: it does candidate generation and leaves resolution, filtering, and reporting to other Unix-style tools.
Timeline
- 2026 batch: Official README documents DNSGen 2.0 and Homebrew input metadata lists a packaged CLI.
- Current README: Project documents Python package installation and development setup through pip, uv, and Git.
