This example will show you how to get the list of domain names on same IP. There might be some situations where you want to host your site and may be interested in knowing the other sites hosted on same domain. This code will help you then..,Happy Coding …

<?php

function reverseIP($IP)
{
	for($f=0; $f <= 2; $f++)
	{
		// this will list the results in the first two page...alter the code to get results from more number of pages
		$url='http://www.bing.com/search?q=ip%3A'.$IP.'&amp;first='.$f.'1&amp;FORM=PORE';
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER[‘HTTP_USER_AGENT’]);
		curl_setopt($ch, CURLOPT_REFERER, "http://yahoo.com/");
		curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 5);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_TIMEOUT, 20); // times out after 15s
		$searchResults= curl_exec($ch);
		curl_close($ch);
		$parsedData=explode("<li>",$searchResults);
		$cntArray=count($parsedData);
		for($x=0;$x<$cntArray;$x++)
		{
			if (preg_match('#<cite>(.*?)</cite>#i',$parsedData[$x], $matches))
			{
				$fullURL[]=$matches[1];
			}
		}

		$cntURL=count($fullURL);

		for($y=0; $y < $cntURL; $y++)
		{
			$result=explode('/',$fullURL[$y]);
			$TLD[]=$result[0];
		}

	}
	$uniqueTLDList=@array_unique($TLD); // we just want the unique domain names
	return $uniqueTLDList;
}
echo '</li>';
// specify the IP of your interest
$arr=reverseIP('69.162.116.154');
$size=sizeof($arr);
for($i=0;$i<$size;$i++) {
echo $arr[$i].'<br>';
}
