WMI Query to retrieve only active IPv4 address

My turn to ask a question. I am running BGInfo for all workstations but at this stage want to only return the Active IPv4 address. I have a custom WMI query set up in BGInfo:

SELECT IPAddress FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'True'

This will return both IPv4 and v6 addresses. Without disabling IPv6 on my client workstations, is there a way I can get the query to return only the IPv4 address? Or should I instead create a custom vbscript in BGInfo to get the v4 address.

Cheers
