Hi @Aetemaad Hussain

Greetings & Welcome to the Microsoft Q&A forum! Thank you for sharing your query.

According to this documentation: Find the IP addresses

To find the internal IP addresses for the FQDNs in the virtual network, you can use Azure CLI, Azure Powershell or Azure Portal. Here are the steps to follow in azure CLI.

1. First, get the ID of the private endpoint network interface by running the following command:

      az network private-endpoint show --name <endpoint> --resource-group <resource-group> --query 'networkInterfaces[*].id' --output table
   

2. Then, use the ID obtained from the previous step to get the IP address and fully qualified domain names (FQDNs) associated with your workspace:

      az network nic show --ids <resource-id> --query 'ipConfigurations[*].{IPAddress: privateIPAddress, FQDNs: privateLinkConnectionProperties.fqdns}'
   

This method allows you to efficiently retrieve the IP addresses without manually checking each network interface card (NIC).

Note: Azure Databricks is designed with a dynamic and scalable infrastructure, meaning that IP addresses for the underlying components (such as drivers and workers) are subject to change. Rather than focusing on trying to pin down a specific IP address, the recommended approach is to leverage Azure networking features that allow secure, reliable communication without needing to manage individual IPs.

Best Practices for Secure and Reliable Connectivity:

The best way to securely access your Azure Databricks workspace from within your VNet is by using Private Endpoints. A private endpoint creates a private, secure connection between your VNet and the Databricks control plane, without relying on public IP addresses. Private endpoints allow secure communication between your Databricks workspace and other resources in your VNet, such as Azure storage or virtual machines (VMs).

If your Databricks workspace needs to access Azure Storage (e.g., Blob Storage or Data Lake), consider using Service Endpoints. Service endpoints allow secure access to Azure services over the Azure backbone network without needing to expose public IP addresses.

You should access your Databricks workspace through its provided workspace URL (e.g., https://<your-workspace-name>.azuredatabricks.net). This is the standard and most reliable way to connect to your Databricks environment, regardless of the underlying IPs.

Since you’ve configured your workspace with a VNet and subnet, your Databricks workspace should use private IP addresses for communication within the VNet. This setup ensures that traffic remains secure and confined to your internal Azure network.

If you need to connect your Databricks workspace to an on-premises network, use VPN Gateway or ExpressRoute to establish a secure, private connection between your on-premises network and your Azure VNet. Again, this eliminates the need for individual Databricks node IPs.

This approach is the recommended and best practice for managing Azure Databricks in a VNet and ensures that your communication remains secure, reliable, and scalable.
