Overview

F5 BIG-IP DNS is designed to hyperscale and secure your DNS infrastructure, ensuring high availability and performance during high query volumes and DDoS attacks. It provides unmatched DNS performance, scalability, and security, making sure applications are highly available across multiple instances and hybrid environments.

Features

High Performance

• Hyperscales authoritative DNS up to 100 million query responses per second (RPS).
• DNS Express improves standard DNS functions by offloading DNS responses and scaling from hundreds of thousands to over 50 million RPS. On-Demand Scaling
• Deploys on-demand scaling with rate limit and object limit capacity.
• Ensures top application performance for users. Global Performance
• Directs users to servers that deliver the fastest, most reliable connection based on business policies, user locations, and app/server performance.
• Utilizes IP Anycast integration to distribute DNS request load and direct single IP requests to multiple local devices. Security
• Protects against volumetric DDoS attacks such as UDP floods or amplification attacks.
• DNSSEC protects LDNS servers from cache poisoning and man-in-the-middle attacks.
• Decrypts and resolves DNS queries over HTTPS (DoH) and ensures DNS requests and responses are not tampered with via DNS over TLS (DoT). Caching and Resolving
• Reduces DNS latency by enabling a DNS cache on BIG-IP DNS, responding immediately to client requests.
• Consolidates the cache to increase the cache hit rate, reducing DNS latency by up to 80%. Location-Based Routing
• Routes clients to the nearest data center with geolocation-based load balancing.
• Enhances user experience by directing traffic to the optimal location.

Benefits

• Enhanced Performance: Ensures high-speed DNS query responses and reduces latency, improving user experience.
• Scalability: Provides on-demand scaling to handle rapid increases in DNS queries.
• Robust Security: Protects against various DNS threats, including DDoS attacks and DNS cache poisoning.
• Operational Efficiency: Simplifies DNS management with centralized control and efficient traffic distribution.
• Improved Reliability: Ensures applications remain highly available and responsive across multiple environments.
