Multicast in java

[pb2000]

Hello,

I work with Client/Server example as below:

public class Client {
public static void main(String[] args) throws IOException,
ClassNotFoundException {
InetAddress address = InetAddress.getByName("225.6.7.8");
MulticastSocket socket = new MulticastSocket(56565);
socket.joinGroup(address);
byte[] buffer = new byte[1024];
DatagramPacket datagram =
new DatagramPacket(buffer, buffer.length);
socket.receive(datagram);
System.out.println(">>> " + datagram.getData()[0]);
socket.leaveGroup(address);
}
}

public class Server {
public static void main(String[] args) throws IOException,
ClassNotFoundException {
InetAddress address = InetAddress.getByName("225.6.7.8");
DatagramSocket socket = new DatagramSocket();
byte[] buffer = new byte[1024];
buffer[0] = 123;
DatagramPacket datagram =
new DatagramPacket(buffer, buffer.length, address, 56565);
socket.send(datagram);
System.out.println("<<< " + datagram.getData()[0]);
}
}

Is it possible to run those on computers belonging to simple lan?. For instance:
10.10.5.2
10.10.5.9

Possibly I did not understand multicast correctly - (should be just logical network over normal physical IP of B,C class)?

Solved. Sorry for stupid question. I am newbie at networking.
