DNS Traffic Management (BIG-IP v11.4+, v12: LTM)

This F5 deployment guide contains guidance on configuring the iApp in BIG-IP system version 11.4 and later for intelligent traffic management for DNS servers, resulting in a secure, fast, and available deployment.

The BIG-IP system provides more sophisticated ways to receive and respond to DNS requests than standard DNS load balancing. The BIG-IP Local Traffic Manager (LTM) uses advanced monitors to ensure traffic is only sent to available DNS servers that are responding with the correct records, and includes built-in protection against DNS denial-of-service attacks.

The following diagram shows the configuration described in this deployment guide.
