-## Reduce DNS alerts
-
-*Learn* unauthorized internet alerts in bulk by FQDN - fully qualified domain names - to reduce the noise of triggered internet alerts in the OT network.
-
-By defining an FQDN allowlist, the system checks each instance of unauthorized internet connectivity attempt against it. If the FQDN is included in the allowlist, then the network will *learn* this alert automatically without triggering it. 
-
-The FQDN list will remain intact through version upgrades.
-
-**To define an FQDN allowlist:**
-
-1. Sign in to your OT network sensor console as the **support** [user](references-work-with-defender-for-iot-cli-commands.md), then select **Support**.
-
-1. In the search bar, search for "DNS", then look for "Internet Domain Allowlist" under **Description**.

-
-You can view to the FQDN allowlist in the advanced configurations and in a [data mining report](how-to-create-data-mining-queries.md). A custom Data mining report will present the FQDN, IP addresses, and last resolution time.

-**To view in a data mining report:**
-
-[Create a custom data mining report](how-to-create-data-mining-queries.md#create-an-ot-sensor-custom-data-mining-report) and make sure to select **Internet Domain Allowlist** under **DNS** when choosing a category in the **Create new report** pane.
