White List Settings
The White List option allows adding DNS addresses that will never be blocked and are not counted towards detection
statistics. If HP Connection Inspector generates false positives the DNS names or domains that cause the false positives
can be added to the white list.

Protected Mode
Entering Protected Mode
The device enters Protected mode when the following conditions are met:
• The number of unique, non-resolved, unknown DNS requests exceeds the DNS Failure Threshold setting.
DNS Behavior in Protected Mode
DNS resolution is allowed for
• A user-defined whitelist of domains and associated domain suffixes
• Domains that have successfully resolved since system startup contained in the History List
• Destinations in the current domain and associated domain suffixes
• Trusted domains (when Cross Origin Resource Sharing is enabled)
When a device is in Protected Mode, DNS requests that are not in the History or Whitelist are not permitted.
