About:
Knot DNS is an authoritative-only DNS server designed for high performance and robustness. It excels in serving large zones with rapid updates and offers features like DNSSEC signing, on-the-fly signing, and efficient zone processing. Its architecture is optimized for modern multi-core systems, making it ideal for TLD and large enterprise DNS operations.
Key Features:
  • High-performance authoritative-only service
  • DNSSEC support with on-the-fly signing
  • Dynamic updates and zone transfer support
  • Optimized for multi-core processors
Use Cases:
  • Running Top-Level Domain (TLD) registries
  • Hosting high-traffic authoritative enterprise DNS zones
  • Secure DNS (DNSSEC) deployment for critical infrastructure
Alternatives:
