Securing DNS infrastructures from the latest distributed denial-of-service (DDoS) attacks and protecting DNS query responses from cachepoisoning redirects will help keep your business online and viable. To fully achieve these goals, you need efficient ways to monitor DNS infrastructure and application health, and to scale on-demand. F5® BIG-IP® DNS distributes DNS and user application requests based on business policies, data center and cloud service conditions, user location, and application performance. The BIG-IP platform delivers F5’s high-performance DNS services with visibility, reporting, and analysis; hyperscales and secures DNS responses geographically to survive DDoS attacks; delivers a real-time DNSSEC solution; and ensures high availability of global applications in all cloud environments. KEY BENEFITS Hyperscale DNS up to 100 million RPS with a fully loaded chassis BIG-IP DNS hyperscales authoritative DNS up to 100 million query responses per second (RPS) and controls DNS traffic. It ensures that users are connected to the best site and delivers on-demand scaling for DNS and global apps. Protect against DNS attacks and ensure availability Ensure DNS and application availability and protection during DNS DDoS attacks or volume spikes. Mitigate DNS threats by blocking access to malicious IP domains. Improve global application performance Send app users to the cloud or on-premises site with the best performance based on application, geolocation, business, and network conditions. Deploy flexibly, scale as you grow, and manage efficiently BIG-IP DNS delivers flexible global application management in virtual and multi-cloud environments. The web-based UI provides easy DNS configuration with centralized menus; advanced logging, statistics, and reporting along with export to 3rd party analytics. UNMATCHED DNS PERFORMANCE BIG-IP DNS delivers hyperscale performance that can handle even the busiest apps and websites. When apps have a volume spike in DNS queries due to legitimate requests or DDoS attacks, BIG-IP DNS manages requests with multicore processing and F5 DNS Express™, dramatically increasing authoritative DNS performance up to 50 million RPS to quickly respond to all queries. This scalability helps your organization provide the best quality of service (QoS) for your users while eliminating poor application performance. DNS Express improves standard DNS server functions by offloading DNS responses as an authoritative DNS server. BIG-IP DNS accepts zone transfers of DNS records from the primary DNS server and answers DNS queries authoritatively. Benefits and features of multicore processing and DNS Express include: • High-speed response and DDoS attack protection with in-memory DNS • Authoritative DNS replication in multiple BIG-IP or DNS service deployments for faster responses • Authoritative DNS and DNSSEC in multi-clouds for disaster recovery and fast, secure responses • Scalable DNS performance for quality of app and service experience • The ability to consolidate DNS servers and increase ROI In cases of very high volumes for apps and services or a DNS DDoS attack, BIG-IP DNS with DNS Express enabled plus in Rapid Response Mode (RRM) hyperscales up to 100 million RPS. It extends availability with unmatched p

FAQs

What performance capabilities does BIG-IP DNS provide for high DNS query volumes?

BIG-IP DNS supports hyperscale authoritative DNS up to 100 million query responses per second (RPS). With multicore processing and DNS Express, it can increase authoritative DNS performance dramatically and handle major volume spikes.

How does BIG-IP DNS reduce DNS latency and improve cache efficiency?

Enabling DNS caching allows BIG-IP DNS to respond immediately to client requests and consolidate caches to raise the cache hit rate, reducing DNS latency by up to 80%. It also supports caching profiles such as transparent cache, hot cache, and validating caching resolver.

How does BIG-IP DNS protect applications and DNS traffic from attacks?

BIG-IP DNS provides protection against DNS DDoS attacks and threats like cache poisoning and DNS hijacking. It includes features such as hardened device resilience, protocol validation to drop high-volume UDP and malformed packets, and policy-based controls to add protection for applications and data.
