dnsFookup

Red team operators and security researchers validating DNS rebinding vulnerabilities in their own infrastructure will find dnsFookup indispensable; it's purpose-built for testing this specific attack surface rather than bolted onto a general-purpose toolkit. The 253 GitHub stars and active maintenance signal it's trusted by practitioners who regularly demo this vulnerability class to stakeholders. Skip this if you need production monitoring or detection controls; dnsFookup is offensive tooling, not defensive, and assumes you already own the systems you're testing against.
