* Address identifies cluster member. For example, whenever a unicast message is sent in a cluster
* an Address of a cluster member message recipient needs to be specified. Similarly a cluster
* member can use Address to check its own identity, request a state from a particular member and so
* on. Addresses are mostly generated by the bottom-most (transport) layers (e.g. UDP, TCP,
* LOOPBACK).
