Define the IP address ranges and domain names used byCortex XDR to identify your network assets.

To track and identify assets in your network, you need to define your internal IP address ranges and domain names to enable Cortex XDR to analyze, locate, and display assets.

Define IP Address Ranges
  1. In Cortex XDR , select AssetsNetwork ConfigurationIP Address Ranges.

  2. Define an IP Address Range.

    By default, Cortex XDR creates Private Network ranges that specify reserved industry approved ranges. Private Network ranges are marked with a assets-private-network.png icon and can only have the name edited.

    To Add New Range select either.

    • Create New

      • In the Create IP Address Rage pop-up, enter the IP address Name and IP Address Range or CIDR values.


        You can add a range which is fully contained in an existing range, however you cannot add a new range which partially intersect with another range.

        The range names you define will appear when investigating the network related events within the Cortex XDR console.

      • Save your definitions.

    • Upload from File

      • In the Upload IP Address Ranges pop-up, drag and drop or search for a CSV file listing the IP address ranges. Download example file to view the correct format.

      • Add your list of IP address ranges.

  3. Review your IP address ranges.

    • Active Managed Assets—Number of assets located within the defined range that are reported Cortex XDR Agent logs.

    • Modified By—User name of user who last changed the range.

    • Modification Time—Timestamp of when this range was last changed.

  4. Manage your IP address ranges.

    In the IP Address Ranges table, locate your range and select:
