import java.net.*;

public class CurrentHost {

  public static void main(String[] args) throws UnknownHostException {

    InetAddress address = InetAddress.getLocalHost();
    System.out.println("This host's name: " + address.getHostName());
    System.out.println("This host's fully qualified address: " +
      address.getCanonicalHostName());
    System.out.println("This host's numerical address: " +
      address.getHostAddress());
  }
}
