We have Cassandra cluster with 5 nodes hosted in the Amazon EC2, and  I had to restart two of them, so their IPs changed.
We use NetworkTopologyStrategy, so I simply updated IPs in the cassandra-topology.properties file.

Set auto_bootstrap:false in the conf file and restart the node to change IP address for a node.
