Any shared IP finder uses some kind of shared storage (S3, shared FS, etc.) to store coordinates of alive nodes. These coordinates are then used by nodes that are trying to join topology. So when a node joins, it reads available IPs from this storage, uses one of them to connect to topology and writes its own IP and port to the storage. When a node leaves, it removes its record. In your scenario you will have to start the node with different configuration (different S3 bucket, different shared FS folder, etc., depending on what type of IP finder you're using).
