Create a virtual machine with a static private IP address using the Azure CLI

A virtual machine (VM) is automatically assigned a private IP address from a range that you specify. This range is based on the subnet in which the VM is deployed. The VM keeps the address until the VM is deleted. Azure dynamically assigns the next available private IP address from the subnet you create a VM in. Assign a static IP address to the VM if you want a specific IP address in the subnet.

  • This tutorial requires version 2.0.28 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Create a resource group

An Azure resource group is a logical container into which Azure resources are deployed and managed.

Create a resource group with az group create named myResourceGroup in the eastus2 location.

  az group create \
    --name myResourceGroup \
    --location eastus2

Create a virtual machine

Create a virtual machine with az vm create.

The following command creates a Windows Server virtual machine. When prompted, provide a username and password to be used as the credentials for the virtual machine:

  az vm create \
    --name myVM \
    --resource-group myResourceGroup \
    --public-ip-address myPublicIP \
    --public-ip-sku Standard \
    --image MicrosoftWindowsServer:WindowsServer:2019-Datacenter:latest \
    --admin-username azureuser

Change private IP address to static

In this section, you'll change the private IP address from dynamic to static for the virtual machine you created previously.

Use az network nic ip-config update to update the network interface configuration.

The following command changes the private IP address of the virtual machine to static:

  az network nic ip-config update \
    --name ipconfigmyVM \
    --resource-group myResourceGroup \
    --nic-name myVMVMNic \


From within the operating system of a VM, you shouldn't statically assign the private IP that's assigned to the Azure VM. Only do static assignment of a private IP when it's necessary, such as when assigning many IP addresses to VMs.

If you manually set the private IP address within the operating system, make sure it matches the private IP address assigned to the Azure network interface. Otherwise, you can lose connectivity to the VM. Learn more about private IP address settings.

Clean up resources

When no longer needed, you can use az group delete to remove the resource group and all of the resources it contains:

  az group delete --name myResourceGroup --yes
