@Varma

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well. I understand that you would like to change the IP Address of VMs to a Static One via Powershell (in same ResourceGroup)

Below PowerShell script can do the trick, as long as,

• The VMs are not part of Load Balancer Rules or Load Balancer Backend Pool
• The VMs do not have a Public IP Address associated to them
• You are updating the first IPconfig of a single NIC VM.

$vms = Get-AzVM -ResourceGroupName "<RGNAME>"


foreach ($vm in $vms)
{

$nic = Get-AzNetworkInterface -ResourceId $vm.NetworkProfile.NetworkInterfaces.Id

#This enables you to set the IP you want as user input for the VM
Write-Host "Current IP of the VM " $vm.Name " is " $nic.IpConfigurations.PrivateIpAddress 
$privateip = Read-Host "Enter the IP you want to set it to"

#Set the NIC to update changes
$nic | Set-AzNetworkInterfaceIpConfig -Name $nic.IpConfigurations.Name -PrivateIpAddress $privateip -SubnetId $nic.IpConfigurations.Subnet.Id 
$nic | Set-AzNetworkInterface


}

In case there are Public IP Addresses, the "Set the NIC to update changes" section becomes :

#Set the NIC to update changes
$nic | Set-AzNetworkInterfaceIpConfig -Name $nic.IpConfigurations.Name -PrivateIpAddress $privateip -SubnetId $nic.IpConfigurations.Subnet.Id -PublicIpAddressId $nic.IpConfigurations.PublicIpAddress.Id
$nic | Set-AzNetworkInterface

Similarly, you can add the additional parameters as required : Refer Set-AzNetworkInterfaceIpConfig

Please modify the script according to your environment. Hope this helps.

Thanks,

Kapil

Hi,

Yes, below article has sample powershell code showing how to change dynamic private ip to static private ip:

Change private IP address to static https://learn.microsoft.com/en-us/azure/virtual-network/ip-services/virtual-networks-static-private-ip-arm-ps#change-private-ip-address-to-static

To change multiple you would first get the VMs you want to change and then loop through them, executing the sample code from the above article. If you are unsure how to do looping for this please let me know and I'll make small sample snippet.

You may also use the portal to set a static private IP. Navigate to the VM, click on Network settings blade, next on right half click on the Network interface / IP configuration, next click on the IP configuration (ipconfig1 in below sample) you want to change. A flyout screen will open on right where you can change it from Dynamic to Static and enter the address you want.

Please click Accept Answer and upvote if the above was useful.

Thanks.

Hi @Varma ,

maybe this example is helpful to set a private IP address to static on an Azure VM via PowerShell:
