+> Avoid breaking connectivity when adding IP addresses  
+> When adding additional IP configurations to a VM, you **do not need to convert the existing (primary) private IP address from Dynamic to Static**.  
+> 
+> Changing the primary IP allocation type can disrupt RDP/SSH connectivity and may require recovery steps such as adding a temporary IP address. This is unnecessary when your goal is only to add secondary IP addresses.
+>
+> Recommended approach:
+> - Leave the primary private IP configuration unchanged.
+> - Add new **secondary IP configurations** (static or dynamic) directly to the NIC.
+> - Only change the primary IP to Static if a fixed primary address is explicitly required and you understand the impact.
