Question: I work with RMI now and need to implement a new feature into software that was written by another people one year ago. I need to find out: what is IP address of a client and then connect or reject the connection. I do not want to add methods to client... It must be the way how to find out it using RMI methods. Unfortunately I did not find with first attempt.

Answer: Your RMI server extends UnicastRemoteObject that extends java.rmi.server.RemoteServer.
That class (RemoteServer) has public static String getClientHost() method.
When called from a thread actively handling a remote method invocation the hostname of the client is returned.

Then use public static InetAddress getByName(String host) method of java.net.InetAddress
Be aware that you do need to try to create an instance of InetAddress. It is static.
Just get it!
