How to get the public IP range of my Azure Databricks cluster? I Need to whitelist this IP range with a host that I want to connect and get data from.

If you need to whitelist the public IP address or IP range used by an Azure Databricks cluster, the important thing to know is that there isn't necessarily one fixed public IP for every Databricks workspace.

Microsoft provides the current Azure Databricks IP ranges by region, including the addresses used for Databricks control-plane and related services. The Microsoft Q&A discussion you referenced points users to these official IP lists.

For a more reliable setup, Microsoft recommends using the Azure Databricks service tag where possible rather than manually maintaining a list of individual IP addresses. Service tags are maintained by Azure, so you don't have to keep updating your firewall rules whenever the underlying IP ranges change.

If your requirement is specifically to allow outbound traffic from your Databricks cluster to an external system, the better approach is to configure a stable egress public IP, for example by using a NAT Gateway with a VNet-injected Azure Databricks workspace. This gives you a predictable public IP that can be added to the external system's allowlist. Microsoft currently recommends this approach for stable egress scenarios.

You can also quickly check the public IP that your current connection appears to use with this IP address checker. Keep in mind, though, that this shows the IP address of the connection from which you access the website—not necessarily the outbound IP address of your Azure Databricks cluster.

In short: if you're trying to whitelist Databricks traffic on a third-party server, don't rely on a generic “what is my IP” website to determine the Databricks IP. Check the Azure Databricks networking configuration for your workspace and, if you need a permanent allowlist entry, use a stable egress IP/NAT Gateway.
