How a device finds encrypted DNS by itself
TL;DR
Discovery of Designated Resolvers (DDR) enables devices to automatically find encrypted DNS settings, enhancing security by encrypting DNS queries. This process allows devices to connect to preferred encrypted endpoints without manual configuration.
✦ Why It Matters
Implement DDR in your network to enhance DNS security without manual configuration.
Key Takeaways
- Implement DDR for automatic encrypted DNS discovery.
- Use encrypted DNS settings for devices with limited configuration options.
- Ensure devices can transition from unencrypted to encrypted DNS seamlessly.
- Configure encrypted resolvers directly for maximum security.
How It Works
DDR allows devices to query a special DNS name, _dns.resolver.arpa, to discover available encrypted DNS endpoints. Resolvers respond with details about these endpoints, including their hostnames and protocols, enabling devices to select the best option based on their capabilities.
