# Configure Cortex XDR network parameters
Define your internal IP address ranges and domain names to enable Cortex XDR to identify, track, and analyze network assets.
**Define internal IP address ranges**
The **IP Address Ranges** page displays the address ranges that Cortex XDR Analytics monitors. Addresses are pre-populated with the default IPv4 and IPv6 address spaces. The names you define appears when investigating the network-related events in Cortex XDR.
You can add a new IP address range manually or upload IP address ranges from a CSV file.
How to define internal IP address ranges
1. Select **Inventory** → **Assets** → **Network Configuration** → **Internal IP Address Ranges**.
2. Do one of the following:
| To | Do this |
| ---------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Add a new IP address manually | 1. Click Add New Range → Create New, and then enter the IP address name and IP address range or CIDR values.
By default, Cortex XDR creates Private Network ranges that specify reserved industry-approved ranges. Private Network ranges are marked with a 
icon and you can only edit the name.
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 IP address ranges from a CSV file | 1. Select Inventory+Assets → Network Configuration → IP Address Ranges.
2. Click Add New Range → Upload from File.
3. Locate the CSV file you want to upload, and then click Add.
|
**Define internal domain names**
1. Select **Inventory** → **Assets** → **Network Configuration** → **Internal Domain Suffixes**.
2. Type the domain suffix you want to include as part of your internal network, for example, **`acme.com`**.
3. Select  to add the suffix to the **Domains List**.

## 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-5.x/configure-cortex-xdr/configure-and-deploy-cortex-xdr/configure-cortex-xdr-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.
