# Step 1, filter network adapters to those that are IP & DHCP enabled
# - this can only be done with the Win32_NetworkAdapterConfiguration class:
Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration  -Filter 'IpEnabled=True AND DhcpEnabled=True'

# To get a unique handle to any/all network adapters matching the filtered query, retrieve only their Index propery:
(Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration  -Filter 'IpEnabled=True AND DhcpEnabled=True').Index

# Using the Index property, enumerate objects in the Win32_NetworkAdapter class, with the same Index (aka DeviceID) property:
# - notice the prior Get-CimInstance query gets wrapped in another $(), to force returning only the resulting value into this Filter statement
# - I added | Format-List, because the default Table formatted results truncated the value of the .Name property
