About DNSDumpster

DNSDumpster takes a domain name and maps the DNS records and hosts associated with it, showing what an outsider can see through passive reconnaissance. It is run by HackerTarget.

Penetration testers and bug bounty hunters use it to map an organisation's attack surface, while network defenders and administrators can use it to check which of their own hosts are publicly visible. A basic search is free and runs in the browser; an account login is offered.

Strengths

  • Nothing to install
  • Quick overview of a domain's visible hosts
  • Passive reconnaissance without touching the target directly

Limitations

  • Intended for authorized testing and checking your own domains
  • Results depend on publicly available DNS data
