Do you have any faster ps script to get azure private ip address?

So, there's two paths you can take with the resource group question:

1. Use the -ResourceGroup parameter on Get-AzNetworkInterface; or
2. Use client-side filtering on the ResourceGroup parameter.

They are both useful in different circumstances.

Using the -ResourceGroup parameter

This is useful if your script is only going to work with this one specific resource group.

The benefit to this approach is that the filtering happens server-side making it faster to run.

Here's an example:

Get-AzNetworkInterface -ResourceGroup "SomeRgName" | Where-Object { $_.VirtualMachine -and $_.IPConfigurations -and $_.IPConfigurations.PrivateIPAddress } | Select-Object -Property ResourceGroupName, @{n="Name"; e={ $_.VirtualMachine.Id.Split("/")[-1] }}, @{n="PrivateIPAddress"; e= { $_.IpConfigurations.PrivateIPAddress }}

Using client-side filtering

Client-side filtering is useful where you may be looking to work with multiple resource groups, even if that's doing so one resource group at a time.

In this scenario, you might be better off pulling all the interfaces down locally once and assigning them to a variable, then repeatedly using client-side filtering so that you're not making unnecessary calls back to Azure.

Client-side filtering can be done a number of different ways. Here's two examples:

Filtering on the original call to Azure

Get-AzNetworkInterface | Where-Object { ($_.ResourceGroupName -in @("RgName01", "RgName02", "RgName03")) -and  ($_.VirtualMachine -and $_.IPConfigurations -and $_.IPConfigurations.PrivateIPAddress) } | Select-Object -Property ResourceGroupName, @{n="Name"; e={ $_.VirtualMachine.Id.Split("/")[-1] }}, @{n="PrivateIPAddress"; e= { $_.IpConfigurations.PrivateIPAddress }}

Assigning to a variable then filtering later

$PrivateIPAddressInfo = Get-AzNetworkInterface | Where-Object { $_.VirtualMachine -and $_.IPConfigurations -and $_.IPConfigurations.PrivateIPAddress } | Select-Object -Property ResourceGroupName, @{n="Name"; e={ $_.VirtualMachine.Id.Split("/")[-1] }}, @{n="PrivateIPAddress"; e= { $_.IpConfigurations.PrivateIPAddress }};

$PrivateIPAddressInfo | Where-Object { $_.ResourceGroupName -in @("RgName01", "RgName03") } | ForEach-Object {
   # Do stuff.
}

$PrivateIPAddressInfo | Where-Object { $_.ResourceGroupName -eq "RgName02" } | ForEach-Object {
   # Do different stuff.
}

This approach means you can keep re-using the data from the variable, which - as mentioned before - avoids having to make multiple calls to Azure, though it only makes sense where the variable's used a lot (my example is too basic to benefit from doing this.)
