Hey I m using above methods bt the getHostName() method is not returning the host name of given ip.

see code:

try {
//        This is ip of tutorialspoint.com    
           InetAddress addr2 = InetAddress.getByName("127.64.84.2");     
            op.setText("Host name is: "+addr2.getHostName());
        }   
        catch ( UnknownHostException e3) {  
            op.setText("Error: Host not found" + e3);
        }

Try this out....

System.out.println(InetAddress.getByName("IP_ADDR").getHostName());

You can use getHostName() method of InetAddress class.

Something like this should point you in the right direction: 

import java.net.InetAddress;
import java.net.UnknownHostException;

public class DNSLookup {
  public static void main(String args[]) {
    try {
      InetAddress host;
      if (args.length == 0) {
        host = InetAddress.getLocalHost();
      } else {
        host = InetAddress.getByName(args[0]);
      }
      System.out.println("Host:'" + host.getHostName()
          + "' has address: " + host.getHostAddress());

    } catch (UnknownHostException e) {
      e.printStackTrace();
    }
  }
}

Yes, its possible.

import java.net.*;
public class HostName
{
  public static void main(String args[])
  {
    InetAddress inetAddress =InetAddress.getByName("127.64.84.2");//get the host Inet using ip
    System.out.println ("Host Name: "+ inetAddress.getHostName());//display the host
  }
}
