                                exec("host -t ns $domain",$hasil);

                                if (ereg("host not found.",strtolower(trim($hasil[0])))) 

                                // It possible only 1 ns or not found

                                {

                                    return false;

                                } else

                                {

                                    $hasilstr="";

                                    for ($i=0;$i<=count($hasil);$i++)

                                    {

                                    $hasilstr.=ereg_replace("$domain name server","<LI>",$hasil[$i])."<BR>";
