Minimize DNS queries by enforcing a minimum TTL (Time to live).
Some DNS answers are set with very low TTL to force DNS recursive resolvers like us to refresh them very often. Low TTLs also force end-clients (your devices) to perform new DNS requests on almost every use.
When Cache Boost is enabled, a minimum TTL of 300 (5 minutes) is enforced on DNS answers before they are sent to your devices. Our servers will still refresh those entries at the requested frequency, but it won’t force your devices to perform more queries than necessary. This is especially interesting on mobile devices with high latency to DNS and limited battery life.
