How To Find Other Web Sites Hosted on a Web ServerCurrently offers free and unlimited if you use to get websites with the same IP address you can use directly on by querying{ip address} (example: or you can use php code to filter only domain names that are not on 

This article uses the following knowledge

  1. file_get_contents: Get data from, you can use curl_init() instead of file_get_contents
  2. preg_match_all: Parse the text to filter out url links
  3. parse_url: parse url to filter out domain names
We will start with the html form. This form is to get data from input IP


<form action="" method="post" class="form-horizontal">
<div class="form-group">
<input type="text" name="ip" id="ip" value="<?=$_POST['ip']?>" class="form-control" placeholder = "Enter IP address server here ..." required/>
<div class="form-group">
<button type="submit" name="submit" class="btn btn-info">Find Now</button>

After receiving the data from the form will put on the query link on'.$_POST['ip']

Note: you must have an IP prefix: before the ip address in the query and you can add count = [10,20, ...50] to get the number of domains you want


$pattern  = "<as[^>]*href=("??)([^" >]*?)1[^>]*>(.*)</a>"; // filter url

This syntax is used to filter the link contained in the returned data, based on which will filter out the domain name

Source Code PHP


$ipServer = $_POST['ip'];
$content  = file_get_contents(''.$ipServer);
$pattern  = "<as[^>]*href=("??)([^" >]*?)1[^>]*>(.*)</a>"; // filter url
if(preg_match_all("/$pattern/siU", $content, $matches, PREG_SET_ORDER)) {
	foreach($matches as $match) {	
		$domain     = parse_url($match[2]);
		$domainHost = $domain[host];
		if($domainHost != '' && $domainHost != '' && $domainHost != '') {
			 $domainServer[] = str_replace('www.','',$domainHost);

print_r( array_unique($domainServer));


In addition, you can use the curl_init() function as below

$url = ''.$ipServer;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$data = curl_exec($curl);
