What does Zscaler enable for DHCP clients in relation to DNS queries?

Zscaler enables DHCP clients to perform direct querying while allowing for re-resolution of DNS queries. This means that when a DHCP client makes a DNS query, Zscaler facilitates a way for this query to be sent directly to the DNS resolver instead of relying on cached responses. This functionality is essential in scenarios where DNS information may frequently change or needs to be verified in real time, ensuring that clients receive up-to-date records without the potential latency or inaccuracies that can arise from cached data.

The ability for clients to re-query or re-resolve DNS addresses leads to better accuracy in network resolution processes. This is particularly valuable in dynamic environments where IP addresses and corresponding DNS records may change due to DHCP leases. Direct querying supports quick responses to DNS requests, enhancing the speed and reliability of DNS resolution for clients.

Considering the context of Zscaler's capabilities, the focus on DNS query management aligns with its mission to improve network security and performance through intelligent traffic routing, thereby securing DNS requests against potential threats while also ensuring optimal performance in accessing necessary resources.
