 There are two ways to view your dbt Cloud IP addresses:
 - If no projects exist in the account, create a new project, and the IP addresses will be displayed during the **Configure your environment** steps.
 - If you have an existing project, navigate to **Account Settings** and ensure you are in the **Projects** pane. Click on a project name, and the **Project Settings** window will open. Locate the **Connection** field and click on the name. Scroll down to the **Settings**, and the first text block lists your IP addresses.

+### Static IP addresses
+
+dbt Cloud, like many cloud services, relies on underlying AWS cloud infrastructure for operations. While we can offer static URLs for access, we cannot provide a list of IP addresses to configure connections due to the nature of AWS cloud services.
+
+* Dynamic IP addresses — dbt Cloud infrastructure uses Amazon Web Services (AWS). dbt Cloud offers static URLs for streamlined access, but the dynamic nature of cloud services means the underlying IP addresses change occasionally. AWS manages the IP ranges and may change them according to their operational and security needs.
+
+* Using hostnames for consistent access — To ensure uninterrupted access, we recommend that you dbt Cloud services using hostnames. Hostnames provide a consistent reference point, regardless of any changes in underlying IP addresses. We are aligning with an industry-standard practice employed by organizations such as Snowflake.
+
+* Optimizing VPN connections &mdash: You should integrate a proxy alongside VPN for users who leverage VPN connections. This strategy enables steady IP addresses for your connections, facilitating smooth traffic flow through the VPN and onward to dbt Cloud. By employing a proxy and a VPN, you can direct traffic through the VPN and then to dbt Cloud. It's crucial to set up the proxy if you need to integrate with additional services.
