Hi there,
hopefully, I can help u out.
Try this method below...
public static String getHost(String ip_addr) {
String host_name = null;
try {
ip_addr = InetAddress.getByName (ip_addr).getHostName();
}catch (UnknownHostException uhe) { }
catch (NullPointerException npe) { }
return ip_addr;
}
For Example, (if you wanna retrieve the host name of 216.115.102.77 )
import java.net.*;
public class TestIp{
public static String getHost(String ip_addr) {
String host_name = null;
try {
ip_addr = InetAddress.getByName (ip_addr).getHostName();
}catch (UnknownHostException uhe) { }
catch (NullPointerException npe) { }
return ip_addr;
}
public static void main(String[] args){
System.out.println(getHost("216.115.102.77"));
}
}
if u get "w5.snv.yahoo.com", BINGO ! :)
if not, sorry.
bye-
Wolfgang.
