The nodes within one datacenter will talk on private IPs and for communication across data center public ips are used. Does that answer your question? or you are asking in terms of network layer.
As per this link <https://docs.datastax.com/en/cassandra-oss/3.0/cassandra/configuration/configMultiNetworks.html>, there is no mention of private IP to be unique. In a network one can assign valid private IP. Private IPs can conflict if we do not put any restriction on private IP.
