DNSGen is a Python CLI tool that generates intelligent permutations of domain names to aid subdomain discovery during security assessments. It applies multiple permutation techniques, including cloud-aware and DevOps-oriented naming patterns, and pipes output to resolvers like massdns.
Use cases
- generate subdomain variations for a target domain
- discover hidden subdomains during a pentest
- expand a domain list before DNS resolution
- find cloud and internal tooling subdomains
- pipe candidate domains into massdns for brute-force resolution
When to choose
- you need fast, flexible DNS name permutation for recon
- you want cloud-aware and microservice naming patterns beyond basic wordlists
- you want a scriptable CLI that fits into a pipeline with resolvers
When to avoid
- you need actual DNS resolution built in rather than candidate generation
- you want a GUI or passive subdomain enumeration from certificate logs
- you need non-DNS asset discovery
