Can WMI query a class property and filter using another class property? - wmi

Question

I am a WMI noob. I'm using BGInfo and have a device with 2 NICs. I'm trying to query the IP address of one of the NICs. I want to submit a query based on the name of the NIC.
However, I'm running into an issue where the IP address is stored in Win32_NetworkAdapterConfiguration and the NIC name is stored in Win32_NetworkAdapter.
I want to build a WMI query like the following:
SELECT IPAddress FROM Win32_NetworkAdapterConfiguration WHERE Win32_NetworkAdapter.Name="My NIC Name".
Is this possible?

Answer 1

For basic understanding, run (from an open cmd window) the following command lines
wmic path Win32_NetworkAdapter get DeviceID, Index, InterfaceIndex, Name, NetConnectionId
wmic path Win32_NetworkAdapterConfiguration get Index, InterfaceIndex, IPAddress
wmic path Win32_NetworkAdapterSetting
and read the following documentation:
Win32_NetworkAdapter class - represents a network adapter of a computer running a Windows operating system (deprecated?),
Win32_NetworkAdapterConfiguration class - represents the attributes and behaviors of a network adapter,
Win32_NetworkAdapterSetting class - association WMI class relates a network adapter and its configuration settings.
Then you can understand how works the following code snippet (if you use a real value for _adapterName instead of the My NIC Name placeholder):
set "_adapterName=My NIC Name"
wmic path Win32_NetworkAdapter where "Name='%_adapterName%'" ASSOC:value /RESULTCLASS:Win32_NetworkAdapterConfiguration
Finally, you can restrict above output to the IPAddress=… line as follows:
wmic path Win32_NetworkAdapter where "Name='%_adapterName%'" ASSOC:value /RESULTCLASS:Win32_NetworkAdapterConfiguration | findstr "^IPAddress"
