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.
Important
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.
How to verify if a specific IP address is available
To verify if the IP address 10.0.0.7 is available in a vnet named TestVnet, run the following PowerShell command and verify the value for IsAvailable:
Test-AzureStaticVNetIP –VNetName TestVNet –IPAddress 10.0.0.7
IsAvailable : True
AvailableAddresses : {}
OperationDescription : Test-AzureStaticVNetIP
OperationId : fd3097e1-5f4b-9cac-8afa-bba1e3492609
OperationStatus : Succeeded
Note
If you want to test the command above in a safe environment follow the guidelines in Create a Virtual Network to create a vnet named TestVnet and ensure it uses the 10.0.0.0/8 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 10.0.0.7 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 10.0.0.7 `
| New-AzureVM -ServiceName "TestService" –VNetName TestVnet
