## 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.

### Related projects

- altdns is named by the README as an inspiration.
- massdns is named by the README for DNS resolution workflows.

## Security Notes

No matching local secret-handling manifest was found for dnsgen. Nucleus package metadata is still published here so future coverage has a stable package URL.
