   <body>
 <center>
   <form action="" method="get">
   <input type="text" value="" name="ip" />
   <input type="submit" value="LOOKUP" />
   </form>
   <?php
 $serverIP = $_SERVER["SERVER_ADDR"];
 echo "Server IP is: <b>{$serverIP}</b><br>";
   function dnsbllookup($ip){
   $dnsbl_lookup=array("dnsbl-1.uceprotect.net","dnsbl-2.uceprotect.net","dnsbl-3.uceprotect.net","dnsbl.dronebl.org","dnsbl.sorbs.net","zen.spamhaus.org");
   if($ip){
   $reverse_ip=implode(".",array_reverse(explode(".",$ip)));
   foreach($dnsbl_lookup as $host){
   if(checkdnsrr($reverse_ip.".".$host.".","A")){
   Host: $listed.=$reverse_ip.'<- Reverse Ip | Your Ip -> '.$ip.' <font color="red">Blacklisted!</font><br /><br>';
   }
   }
   }
   if($listed){
   echo $listed;
   }else{
   echo '<br>'.$ip.' <font color="green">Is not blacklisted!</font><br />';
   }
   }
   $ip=$_GET['ip'];
   if(isset($_GET['ip']) && $_GET['ip']!=null){
   if(filter_var($ip,FILTER_VALIDATE_IP)){
   echo dnsbllookup($ip);
