This episode transcript and blog post explores how DNS has evolved from a simple "phonebook" into a defensive layer (Protective DNS) using Response Policy Zones and threat feeds; it discusses balancing privacy (DoT/DoH) with defender visibility via passive DNS telemetry, outlines Zero Trust DNS and device-centric allow-listing as a portable perimeter, and touches on DNSSEC adoption and the role of human curiosity alongside AI in threat detection.
