# Configure the Data Warehouse IP Allowlist

Use the Data Warehouse IP Allowlist to improve system security and help prevent unauthorized access to your Data Warehouse. Marketing Cloud Personalization permits connections only from the IP ranges on the Allowlist. If the Allowlist is empty, the Data Warehouse doesn’t accept connections from any IP address.

Note The Data Warehouse is available only for customers who have already purchased the Marketing Cloud Personalization - Data Warehouse add-on product.

Data Warehouse IP Allowlist rules apply to all datasets in an account. Marketing Cloud Personalization supports only IPv4 and IPv6 ranges in CIDR notation.

1. From the main navigation menu, select **Security** | **Manage Data Warehouse.**
2. Click the **Data Warehouse IP Allowlist** tab.
3. To add an IP address or range, click **Add IP Range**.
4. Enter an IPv4 or IPv6 range in CIDR notation.
    
    For example: IPv4 range: 54.161.29.212/24, IPv6 range: 2001:db8:1234::/48
5. Enter a short description for the IP range, such as “Office Network”.
6. Save the entry.

To delete an IP range, click the trash can icon.

Example

Specify a range of IP addresses that belongs to your office network. When someone attempts to log in from outside your network, Data Warehouse denies access to that person. An empty IP Allowlist blocks connections from all IP addresses.
