BIG-IP DNS
BIG-IP DNS’ role in the F5 Application Delivery and Security Platform (ADSP) enables your DNS and Global Server Load Balancing (GSLB) infrastructure to deliver a unified, scalable, intelligent framework for application delivery and security, for fast, secure applications across environments.
Scaling, Securing and Optimizing DNS
F5 ADSP maximizes application availability and performance, and provides BIG-IP DNS real-time traffic steering and GSLB through unified management and intelligent orchestration. It hyperscales and secures your infrastructure during high query volumes and DDoS attacks, ensuring reliable performance across hybrid and multicloud environments.
Total security is necessary for every application because applications are the center of attention for both bad actors and legitimate users. A poorly secured network can have damaging consequences, costing customers and revenue. BIG-IP DNS services provide DevOps-friendly agility with the scale, security depth, and investment protection needed for both established and emerging apps.
- DNS Firewall/DDoS - Can be combined with BIG-IP AFM to provide extensive security, including shielding DNS from volumetric DDoS attacks such as UDP floods or amplification DDoS attacks.
- DNSSEC - Protect LDNS servers from cache poisoning and man-in-the-middle attacks with real-time DNSSEC.
- DoH/DoT - BIG-IP DNS decrypts and resolves DNS queries over HTTPS (DoH) without impacting RPS. DNS over TLS (DoT) ensures that DNS requests and responses are not tampered with or forged via on-path attacks.
Networks are growing, both in scale and traffic demands, driving the need for improved availability for users and better access and management for administrators. BIG-IP DNS affords easy visibility and programmability, ensuring network architectures are easier to maintain.
- Integration with current infrastructure - Communicate and integrate with network devices like SNMP agents, third-party caches, servers, routers, and load balancers to diagnose network endpoint health.
- Flexible site options - Enable flexible site options including Active/Active, Active/Passive, or Active/DR Only.
- Failover that ensures availability - Failover whole data centers or individual apps/servers to ensure users have uninterrupted access to the apps they need.
Product Overview
Hyperscale and protect DNS while optimizing global app delivery
DNS enables users to access services, making it one of the most important components in the network infrastructure. If DNS is unavailable, services won’t function properly. Service providers and enterprises need to build an optimized and secure DNS infrastructure with the ability to rapidly scale and deal with millions of service names and IP addresses. Improve the performance and availability of your global applications by sending users to the closest or fastest endpoint—whether that be a physical, virtual, or cloud environment with F5 global server load balancing (GSLB).
Cloud-Native
Available in cloud-native format as a CNF, F5 application services work the same way in the public and private cloud as they do in the data center.
Virtual Editions
BIG-IP VEs have the same features as those that run on F5 hardware—and you can deploy them on any hypervisor or select cloud provider.
Hardware
Both the BIG-IP family of devices and the VELOS chassis are purpose-built, powerful hardware that F5 software runs on.
Core Capabilities
The F5 hyperscale and secure DNS solution provides faster web browsing and reduced latency, improving user experience and leading to reduced churn and increased revenues. Visibility into DNS and these applications mean that their health, optimization, and protection can be maximized.
Superior DNS performance
Manages query responses with multicore scalability, handling spikes in DNS query volumes.
DNS security
Validates query requests, mitigates malicious communications, absorbs DDoS attacks, encrypts end to end with SSL, and more.
Reporting and analytics
Logging, reporting, and analytics - detailed DNS and GSLB data, statistics, and graphs for in-depth analysis.
Global server load balancing
Supports application requirements across data center and cloud environments while keeping apps available.
Continual monitoring and automated failover
Gives you the flexibility to shift traffic to a backup data center and fail over an entire site, or just control the affected apps.
DNS health monitor
Out-of-the-box health monitoring support for applications.
3G, 4G, and 5G 3GPP support
Supports NAPTR DNS nodes and services to drive faster service instantiation.
IPv6 and DNS64 support
Translates traffic for consumption by either IPv4 or IPv6 endpoints.

Private platforms we support
Technology alliances
F5 application services integrate with major cloud providers and are available directly through marketplace offerings with variable PAYG or perpetual BYOL consumption options.
Private platforms we support
F5 supports co-location/interconnection providers when building out private clouds. A private cloud using F5 app services is ideal for speeding app deployments, enabling dynamic changes in the data center, and matching infrastructure services to workloads using a per-app model.
