An important part of asset management is knowing where your assets are, as well as knowing when assets aren't where they should be. Ivanti Neurons for ITAM supplies an Asset Location Exceptions report that identifies when a discovered or imported asset isn't in the location that you may have manually assigned it to in the Hardware Assets workspace. Using the report, you can reassign the asset to the correct location under the **Hardware Assets** workspace > **Details** tab.

Before ITAM can produce the report, you need to create a list of your subnets and associate each one to a location in the **Subnet Mapping** workspace. Alternatively, you can also associate a subnet to a location using the **Locations** workspace > **Subnets** tab. Only Asset Administrators or users with the Asset Manager role can do this.

You can view the report in the **Home** workspace > **Asset Exceptions** dashboard. For details about how to access this dashboard, see [Dashboards](docId:8MLQTuP-AEfwhgTq0Wps-).

**To create a subnet mapping**

1. Open the **Subnet Mapping** workspace and click **New**.

2. Type the subnet address in the **Subnet** field. Do not use CIDR notation for the format.
3. Select a **Location** to associate with this subnet address. The mapping between the subnet and location is used to identify the exceptions. The list of available locations is populated from the Locations workspace.
4. Enter the **Gateway** and **Subnet MAC** for informational use only. These fields are not used in the Asset Location Exceptions report.
5. Click **Save**. Repeat as necessary for each subnet that you want to associate with a location.

Once you're finished, two things will occur:

- In the **Subnet Mapping** workspace, assets discovered in a mapped location will automatically populate the **Assets** tab for that location.
- In the **Locations** workspace, the **Subnets** tab for each mapped location will automatically populate with the information you entered.
