How Local Network Discovery Breaks with Custom DNS

Ever set up a custom DNS resolver like AdGuard Home, only to find your printer or Raspberry Pi mysteriously vanishes from the network? This episode dives into the elegant world of multicast DNS and DNS Service Discovery — the protocols that make zero-configuration networking feel like magic — and explains exactly why they collide with split DNS setups. We trace the failure from query to NXDOMAIN, walk through how macOS, Windows, and Linux each handle .local domains differently, and reveal why the fix isn't what most people expect.
