		System.out.println("Hostname of local machine: " + localMachine.getCanonicalHostName());
		System.out.println("IP of local machine: " + localMachine.getHostAddress());
		java.net.InetAddress localhost = java.net.InetAddress.getByName("localhost");
		System.out.println("Hostname of localhost: " + localhost.getCanonicalHostName());
