Pablo, I think I understand the question, if not reply back.
In our shop, we are getting that information. In my example, the cluster is an sql cluster.
Discovery produces: Name XX2K0610
Type Microsoft Cluster
Internal Identifier blahblah-65f3-40fe-abc0-f6538e1ace2b
Member Hosts
XX2k0610n1
XX2k0610n2
XX2k0610n3
XX2k0610n4
Service Software
Microsoft Cluster Server cluster name: XX2K0610
Microsoft Cluster Server cluster name: XX2K0610
Microsoft Cluster Server cluster name: XX2K0610
Microsoft Cluster Server cluster name: XX2K0610
On this screen if you click on each of the member hosts, you will get that IP. If you ping on the Name XX2K0610, you get the logical IP of the cluster. This is under Infrastructure, clusters.
Hope this answers you question.
