How to set a static internal private IP address using PowerShell (Classic)

In most cases, you won’t need to specify a static internal IP address for your virtual machine. VMs in a virtual network will automatically receive an internal IP address from a range that you specify. But in certain cases, specifying a static IP address for a particular VM makes sense. For example, if your VM is going to run DNS or will be a domain controller. A static internal IP address stays with the VM even through a stop/deprovision state.


Azure has two different deployment models for creating and working with resources: Resource Manager and classic. This article covers using the classic deployment model. Microsoft recommends that most new deployments use the Resource Manager deployment model.

Install the Azure PowerShell Service Management module

Before you run the following commands, make sure that the Azure PowerShell Service Management module is installed on the machine. For the version history of Azure PowerShell Service Management module, see Azure module in PowerShell Gallery.

How to verify if a specific IP address is available

To verify if the IP address is available in a vnet named TestVnet, run the following PowerShell command and verify the value for IsAvailable.

Test-AzureStaticVNetIP –VNetName TestVNet –IPAddress 

IsAvailable          : True
AvailableAddresses   : {}
OperationDescription : Test-AzureStaticVNetIP
OperationId          : fd3097e1-5f4b-9cac-8afa-bba1e3492609
OperationStatus      : Succeeded


If you want to test the command above in a safe environment follow the guidelines in Create a virtual network (classic) to create a vnet named TestVnet and ensure it uses the address space.

How to specify a static internal IP when creating a VM

The PowerShell script below creates a new cloud service named TestService, then retrieves an image from Azure, then creates a VM named TestVM in the new cloud service using the retrieved image, sets the VM to be in a subnet named Subnet-1, and sets as a static internal IP for the VM:

New-AzureService -ServiceName TestService -Location "Central US"
$image = Get-AzureVMImage|?{$_.ImageName -like "*RightImage-Windows-2012R2-x64*"}
New-AzureVMConfig -Name TestVM -InstanceSize Small -ImageName $image.ImageName `
| Add-AzureProvisioningConfig -Windows -AdminUsername adminuser -Password MyP@ssw0rd!! `
| Set-AzureSubnet –SubnetNames Subnet-1 `
| Set-AzureStaticVNetIP -IPAddress `
| New-AzureVM -ServiceName "TestService" –VNetName TestVnet

How to retrieve static internal IP information for a VM

To view the static internal IP information for the VM created with the script above, run the following PowerShell command and observe the values for IpAddress:

Get-AzureVM -Name TestVM -ServiceName TestService

DeploymentName              : TestService
Name                        : TestVM
Label                       : 
VM                          : Microsoft.WindowsAzure.Commands.ServiceManagement.Model.PersistentVM
InstanceStatus              : Provisioning
IpAddress                   :
InstanceStateDetails        : Windows is preparing your computer for first use...
PowerState                  : Started
InstanceErrorCode           : 
InstanceFaultDomain         : 0
InstanceName                : TestVM
InstanceUpgradeDomain       : 0
InstanceSize                : Small

OperationId                 : 34c1560a62f0901ab75cde4fed8e8bd1
OperationStatus             : OK
