+## Enable `AllowBringYourOwnPublicIpAddress` Feature
+
+Before deploying the resources, you may need to enable the **Bring Your Own Public IP Address** feature in Azure. This is required only once per subscription.
+
+### Steps
+
+1. **Run the following command to register the feature:**
+
+   ```bash
+   az feature register --namespace Microsoft.Network --name AllowBringYourOwnPublicIpAddress
+   ```
+
+2. **Wait for the registration to complete.**
+    You can check the status using:
+
+    ```bash
+    az feature show --namespace Microsoft.Network --name AllowBringYourOwnPublicIpAddress --query properties.state 
+    ```
+
+3. **The output should show:**
+    "Registered"
+
+4. **Once the feature is registered, refresh the provider:**
+
+    ```bash
+    az provider register --namespace Microsoft.Network
+    ```
+
+    💡 Note: Feature registration may take several minutes to complete. This needs to be done only once per Azure subscription.
+
+## Steps to avoid `ResourceGroupNotFound` Error

+
