Let’s assume you want to return IP addresses from all network cards but separate them by address type. Here is an approach that uses solely Select-Object:

function Get-IPAddress
{
  Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration |
  Where-Object { $_.IPEnabled -eq $true } |
  # add two new properties for IPv4 and IPv6 at the end
  Select-Object -Property Description, MacAddress, IPAddress, IPAddressV4, IPAddressV6 |
  ForEach-Object {
    # add IP addresses that match the filter to the new properties
    $_.IPAddressV4 = $_.IPAddress | Where-Object { $_ -like '*.*.*.*' }
    $_.IPAddressV6 = $_.IPAddress | Where-Object { $_ -notlike '*.*.*.*' }
    # return the object
    $_
  } |
  # remove the property that holds all IP addresses
  Select-Object -Property Description, MacAddress, IPAddressV4, IPAddressV6 
}

Get-IPAddress

The result looks similar to this:

 
Description                          MacAddress        IPAddressV4   IPAddressV6             
-----------                          ----------        -----------   -----------
