{
  public static void main(String args[])
  {
    InetAddress addr;
    String domaiName,IPAddr;
    try
    {
      addr=InetAddress.getLocalHost();
      domaiName=addr.getHostName();
      IPAddr=addr.getHostAddress();
      System.out.println(domaiName);
      
     
      System.out.println(IPAddr);
     }
     catch(UnknownHostException e)
     { System.out.println("site not found!"); 
     }

}
