    how many nodes are going to be in your cluster? 2, 3, 4?

    As far as IP given out depends on what your clustering

    Generally 2 node cluster,  One for each server of course, one for the Heart Beat, and one for the cluster itself

    Assisted Solution

    Node1- Ip address
    Node2- Ip address
    Heart Beat- IP address
    Cluster itself (Ip address)

    So 4 IP's for a 2 node cluster.
