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. ### Sources - - - source_facts.package-manager ## Security Notes No matching local secret-handling manifest was found for dnsgen.
