Get IP address of VM using vCloud PHP SDK?

I am trying to get the IP address of a VM using the vCloud Director PHP SDK version 1.0.2, you would think that there would be a get_ip( ) method but I cannot find on and searching for a way to gewt the IP address of a vm has taken me down a rabbit hole.  Was curious if anyone had a simple way to get such information?

thanks in advance,

Jason
