When enrolling a new node to an existing cluster, we sometimes need to bind transport to non-localhost addresse. If the other nodes of the cluster are on different hosts than this node, then the default configuration of binding transport layer to localhost will prevent this node to join the cluster even after "successful" enrollment. We check the non-localhost transport addresses that we receive during enrollment and if any of these are not in the list of non-localhost IP addresses that we gather from all interfaces of the current host, we assume that at least some other node in the cluster runs on another host.
