Get current IP addresses associated with an Azure ARM VM's set of NICs via Powershell - powershell

Question

I'm trying to write some Powershell to get a list of Azure ARM vms (Not classic) and the currently associated IP addresses for their NICs.
In classic, this was part of the VM object, but in ARM it's a seperate object, and I'm struggling to get the Powershell to work in the way I want.
I've got the following code segment:
$nic = (((Get-AzureRmVM).NetworkProfile).NetworkInterfaces).Id
ForEach ($i in $nic) {
$nicname = $i.substring($i.LastIndexOf("/")+1)
Get-AzureRmNetworkInterface -Name $nicname -ResourceGroupName RGTEST | Get-AzureRmNetworkInterfaceIpConfig | select-object PrivateIpAddress,PrivateIpAllocationMethod
}
Which works, but only for VMs in the specified resource group 'RGTEST'.
It seems that Get-AzureRmNetworkInterface can only work when passed in the NIC Name and the ResourceGroupName, but I can't seem to get the RGname from the VM to be passed in.
Probably really easy, but I'm struggling with it!

Answer 1

I use this code to get all my ARM VMs, their private IP address and allocation method, it works across resource groups.
$vms = get-azurermvm
$nics = get-azurermnetworkinterface | where VirtualMachine -NE $null #skip Nics with no VM
foreach($nic in $nics)
{
$vm = $vms | where-object -Property Id -EQ $nic.VirtualMachine.id
$prv = $nic.IpConfigurations | select-object -ExpandProperty PrivateIpAddress
$alloc = $nic.IpConfigurations | select-object -ExpandProperty PrivateIpAllocationMethod
Write-Output "$($vm.Name) : $prv , $alloc"
}
Sample Output:
proddc : 10.0.0.4 , Static
stagedc : 10.1.0.4 , Static

Answer 2

Below is the script I used to get the Private and Public IP for an Azure ARM VM. If a VM has more than one NIC or IpConfig it would probably need to use a loop.
$rg = Get-AzureRmResourceGroup -Name "MyResourceGroup01"
$vm = Get-AzureRmVM -ResourceGroupName $rg.ResourceGroupName -Name "MyVM01"
$nic = Get-AzureRmNetworkInterface -ResourceGroupName $rg.ResourceGroupName -Name $(Split-Path -Leaf $VM.NetworkProfile.NetworkInterfaces[0].Id)
$nic | Get-AzureRmNetworkInterfaceIpConfig | Select-Object Name,PrivateIpAddress,#{'label'='PublicIpAddress';Expression={Set-Variable -name pip -scope Global -value $(Split-Path -leaf $_.PublicIpAddress.Id);$pip}}
(Get-AzureRmPublicIpAddress -ResourceGroupName $rg.ResourceGroupName -Name $pip).IpAddress
#Output:
Name PrivateIpAddress PublicIpAddress
---- ---------------- ---------------
ipconfig1 10.0.0.10 MyVM01-pip
40.80.217.1

For those that are looking for a solution that works across multiple subscriptions in a tenant, here's a script that loops through each subscription and reports on each private IP, NIC, VM, Resource Group and associated subscription. The output is in object format and is exported to a CSV file.
<#
.SYNOPSIS
Returns IP addresses and associated network interfaces and virtual machines across all Azure subscriptions the
user has access to.
.DESCRIPTION
This script returns all private IP addresses, the IP configuration resources they are associated with, the network interfaces and virtual
machines across all subscriptions. This script requires:
1. The Azure module to be installed (https://learn.microsoft.com/en-us/powershell/azure/install-az-ps?view=azps-2.8.0)
2. The user to be logged in to an Azure account using Connect-AzAccount / Connect-AzureRmAccount
3. The user must have subscription wide read permissions assigned for each subscription being queried
.PARAMETER FileName
Optional. Specify the file name and path for a CSV export.
.EXAMPLE
Get-IpAddressAllocation.ps1 -FileName .\AzureIpAddressReport.csv

Since this question was asked back in 2016, Microsoft decided to no longer maintain the AzureRM module past Dec 2020, and along with it, the *-AzureRM* cmdlets. The Az module replaces it going forward.
However, there's a fast alternative for retrieving the list of Azure VMs with their associated IPs (private and public ones), by using Azure Resource Graph (ARG).
Concretely, for several thousand VMs, spread across several hundred Azure subscriptions, it takes mere seconds with ARG as opposed to 20+ minutes using Az's Get-AzVM cmdlet.
The script further down will report correctly even on multiple vmNics and multiple IP configurations per vmNic. It will retrieve all ARM VM data across the Azure subscriptions in the tenant. If running from either a local Powershell session or Cloud Shell, make sure you have the Az.ResourceGraph module installed first.
Sample output on a small test Azure tenant:
The script follows:
function RunARGquery {
param (
[string[]]$SubscriptionIds,
[string]$ARG_query
)
$fullResultSet = #()
$pageSize = 5000
# Subscription batching code below taken
# from https://learn.microsoft.com/en-us/azure/governance/resource-graph/troubleshoot/general#toomanysubscription
# Create a counter, set the batch size, and prepare a variable for the results
$counter = [PSCustomObject] #{ Value = 0 }
$batchSize = 1000
# Group the subscriptions into batches
$subscriptionsBatch = $subscriptionIds | Group -Property { [math]::Floor($counter.Value++ / $batchSize) }
$currentBatchNo = 0
# Run the query for each batch
foreach ($batch in $subscriptionsBatch) {
$pagesProcessedSoFar = 0
do {
$results = #()
if($pagesProcessedSoFar -eq 0) {
$results = Search-AzGraph -Subscription $batch.Group -Query $ARG_query -First $pageSize
}
else {
$results = Search-AzGraph -Subscription $batch.Group -Query $ARG_query -First $pageSize -Skip ($pagesProcessedSoFar * $pageSize)
}
$pagesProcessedSoFar++
Write-Host "Processed $pagesProcessedSoFar pages so far. A number of $(($results | Measure-Object).count) results returned in the last page"
$fullResultSet += $results
} while(($results | Measure-Object).count -eq $pageSize)
Write-Host "Finished subscription batch $currentBatchNo"
$currentBatchNo++
}
return $fullResultSet
}
# Get the date/time now, for timestamping both output files
$currentDateTime = Get-Date -Uformat "%Y%m%d-%H%M%S"
Write-Host "Getting list of Azure subscriptions..."
# Fetch the full array of subscription IDs
$subscriptions = Get-AzSubscription
$subscriptionIds = $subscriptions.Id
Write-Host "Found $(($subscriptionIds | Measure-Object).count) subscriptions"

If you're looking to also retrieve the classic Azure VMs (ASM model), using ARG as well, a script is available here. A detailed discussion around the Azure Resource Graph queries for retrieving the VM data, throttling, permissions, etc can be found in this post.

Here's a script that I use to get relevant VM Private/Public IP Address info used for various tasks. It will run from MAC OS or Windows OS as I've a MAC with a Widows 10 Parallels VM running for compatibility. Use it as you wish.
It will export to CSV and attempt to open in Excel or whatever is registered to the CSV extension. In the example below it was saved as PS_AzureRM_Get_VMs.ps1 or just run it as raw code in PowerShell.
#Login to AZURE from PowerShell
#Below works in MAC/Linux PowerShell 6.0.1+ and Windows WMF 4.0+
#pwsh on MAC OS or powershell_ise.exe on Windows
#Connect-AzureRmAccount (Login-AzureRMAcount and Add-AzureRMAccount are the older Azure cmdlets)
# Goto URL https://microsoft.com/devicelogin and the password it provides example Q9KZ3HGN2
# You may need to select-azurermsubscription -subscriptionid $SubscriptionID #Define $SubscriptionID = 'replace everything with your actual subscription xxx-xxxx-xxx'

I have searched a lot and finally succeeded. Using resource group name and azure vm name, you can retrieve private or public ip address:
$Resourcegroup=""
$VmName=""
$VmNetworkdetails= (((Get-AzureRmVM -ResourceGroupName $Resourcegroup -Name $VmName).NetworkProfile).NetworkInterfaces).Id
$nicname = $VmNetworkdetails.substring($VmNetworkdetails.LastIndexOf("/")+1)
$privateIp =(Get-AzureRmNetworkInterface -Name $nicname -ResourceGroupName $Resourcegroup)|Select-Object -ExpandProperty IPConfigurations
write-host $privateIp.PrivateIpAddress
