About:
Massdns is a high-performance DNS stub resolver designed for bulk lookups and reconnaissance. It can resolve massive lists of domains efficiently using a simple text-based interface. The tool is ideal for security researchers and network administrators needing fast, parallel DNS resolution.
Key Features:
  • High-throughput asynchronous DNS resolution
  • Simple configuration via command-line flags
  • Supports multiple output formats (text, JSON, binary)
  • Built-in list processing and filtering capabilities
Use Cases:
  • Performing bulk DNS reconnaissance on large target lists
  • Validating domain resolution across thousands of entries
  • Identifying subdomains during security assessments
Alternatives:
  • masscan – Masscan is a port scanner, whereas Massdns focuses specifically on high-speed DNS resolution.
  • dnsrecon – Dnsrecon focuses on enumeration and zone transfers, while Massdns prioritizes raw bulk resolution speed.
