What should you configure in the system settings to resolve IP addresses to host names in FortiView?

To resolve IP addresses to host names in FortiView, configuring a local DNS server is the optimal choice. A local DNS server typically provides quicker resolution times as it is within the same network or physical location, reducing latency compared to remote solutions. By utilizing a local DNS server, FortiView can efficiently translate IP addresses to their corresponding host names, which enhances the visibility and analysis of the events captured.

When IP resolution occurs locally, it allows for faster access to host name information, which is essential for effective monitoring and reporting within FortiView. This can greatly enhance data interpretation, making it easier for users to identify sources of traffic and events.

In contrast, using a remote DNS server, cloud-based DNS service, or root DNS server would introduce additional latency and potential failure points, as these services rely on external connections. Such configurations might not provide the same efficient and dependable resolution capability needed for timely analysis and reporting.
