Better way to get Microsoft Failover Cluster IP address resource through PowerShell

Question

Is there a better way to view the IP address assigned to cluster IP address resource through PowerShell?

Today, I use Get-ClusterResource, but I have to populate the cluster IP address resource name field with the IP address. That seems weird to me, but it works.

Here is how I get the IP addresses now:

PS C:\Users\Administrator> Get-ClusterResource

Name                    State  OwnerGroup    ResourceType
----                    -----  ----------    ------------
Cluster Name            Online Cluster Group Network Name
IP Address 10.10.10.x Online SRXSVC        IP Address
IP Address 10.10.10.y Online Cluster Group IP Address
IP Address 10.20.70.z Online SRXSVC        IP Address

Welcome to ServerFault. You ask for a "better way". Can you show us the code you currently use? Without knowing that, it's hard to propose something "better". — Doug Deden, Apr 08 '19 at 20:32
I use "Get-ClusterResource | SLS 'IP Address'" and get list of IP address that I parse. I put example in original question. — ptay, Apr 08 '19 at 22:11

This will be a little bit cleaner. It'll return just the IP address.

get-clusterresource -name "cluster ip address" | get-clusterparameter -name Address | select -Property Value

Returns:

Value

I think this is the best way to retrieve the cluster IP address without using explicit names:

Get-ClusterGroup | Where-Object { $_.GroupType -eq "Cluster" } |
    Get-ClusterResource | Where-Object { $_.ResourceType -eq "IP Address" } |
    Get-ClusterParameter -Name "Address" | 
    Select-Object -ExpandProperty "Value"

You can use the following to return the IP address(es):

Get-ClusterResource | Where { $_.ResourceType -eq "IP Address" } | Get-ClusterParameter -Name "Address" | Select ClusterObject, Value
