About:
dnsgen is a Python-based tool that takes a list of existing domain names and generates a highly probable list of valid subdomains. It uses permutation algorithms based on the input domains to discover potential targets during reconnaissance phases.
Key Features:
  • Permutation-based generation from input domains
  • Fast and efficient processing of domain lists
  • Integrates easily into reconnaissance workflows
  • Lightweight Python implementation
Use Cases:
  • Subdomain enumeration during penetration testing
  • Expanding attack surface for bug bounty hunting
  • Reconnaissance for red team operations
Alternatives:
  • massdns – Massdns performs high-speed DNS resolution, while dnsgen focuses specifically on generating candidate names from patterns.
  • dnsrecon – Dnsrecon performs various DNS enumeration methods including zone transfers, whereas dnsgen specializes in name generation.
