Limit Rules


Overview

Limit Rules in Haltdos GSLB enable administrators to control DNS query traffic by setting restrictions on query rates, bursts, and tracking durations. These rules help mitigate traffic spikes, prevent abuse, and maintain optimal performance by defining thresholds for query handling. Limit Rules are flexible, allowing configuration based on specific Fully Qualified Domain Names (FQDNs) or other criteria to ensure network stability and security.
