This enables Cortex XDR to analyze, locate, and display your network assets.
Define internal IP address ranges 1. In Cortex XDR, select **Assets** **Network Configuration**. 2. Define an IP address range. By default, Cortex XDR creates **Private Network** ranges that specify reserved industry-approved ranges. These ranges can only be renamed. To **Add New Range**, select either: * **Create New**. 1. In the **Create IP Address Range** dialog box, enter the IP address **Name** and **IP Address, Range or CIDR values**.

Note

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

2. Click **Save**. * **Upload from File** 1. In the **Upload IP Address Range** dialogue box, drag and drop or search for a CSV file listing the IP address ranges. **Download example file** to view the correct format. 2. Click **Add**.
Define domain names 1. In Cortex XDR , select Assets → Network Configuration → **Internal Domain Suffixes**. 2. In the **Internal Domain Suffixes** section, **+Add** the domain suffix you want to include as part of your internal network. For example, **`acme.com`**. 3. Select ![network-mapper-enter.png](/files/r5MLVZwzOdwySAuNfXIG) to add to the **Domains List**.
IP address ranges fields | FIELD | DESCRIPTION | | --------------------- | ------------------------------------------------------------------------------------------------------------------------- | | Range Name | Name of the IP address range defined. | | First IP Address | First IP address value of the defined range. | | Last IP Address | Last IP address value of the defined range. | | Active Assets | Number of assets within the defined range that have reported Cortex Agent logs or appeared in your Network Firewall Logs. | | Active Managed Assets | Number of assets within the defined range reported Cortex XDR Agent logs. | | Modified By | Username of the user who last changed the range. | | Modification Time | The timestamp shows when this range was last changed. |
--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/detect-threats-and-analyze-data/asset-management/network-configuration/configure-your-network-parameters.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
