how to understand network usage in orchestrator

hello,

I have difficutlies to figure out  standard networks usage on orchestrator if it is host network or vcenter networks

I  have created an attribute with a "network" type and I have selected the value on the orchestrator vc: inventory under a specific cluster and not under the datacenter

when I list all the hosts of this network

networkVar.host

I see in result all the hosts which have a network with this name not only the hosts of the cluster

so how can I find host from a certain cluster which uses this network?

thanks
