Need help with PHP script for IP address of sites

Hi All
I need some assistance with getting the IP address of a web site.

Basically I have to write a PHP page where if a site name is supplied it would return back the IP address of the site as well as specify if the IP Address is Dedicated for that site or a Shared IP Address

I have figured out how to get the IP address of a site in PHP however I am not able to figure out how can I find out whether that IP address is static i.e. dedicated IP for the site or a shared IP that the site is using.

Does anyone know how to get around this problem, using PHP how can I figure out if an IP address of the site is a Dedicated IP address for that site or whether that IP is a shared one.

Any help on this matter is appreciated

Cheers
Asif

What you're looking for is reverse DNS lookup (looking up domain names from ip address)

php uses gethostbyaddr() function for that

http://uk.php.net/gethostbyaddr

from that page, there's this post

While writing a script to verify IP<->hostname loops, I sorely missed the "list" version of gethostbyaddr (similar to gethostbynamel()) and since dns_get_record is a bit too complex for that task alone, I've written a simple wrapper that should behave like gethostbynamel():

function gethostbyaddrl($ip) {
$rrs=dns_get_record(implode('.',array_reverse(explode('.', $ip))).'.in-addr.arpa.',DNS_PTR);
$revnames=array();
foreach($rrs as $rr) $revnames[]=$rr['target'];
return (count($revnames)) ? $revnames : FALSE;
}

Hopefully it'll be of use to someone else, too.

which neatly uses dns_get_record function to pull the associated domains and put them in an array ($revnames) which I think is what you were after - ie, count($revnames > 1) = shared (although $revnames could be equal to one, still shared, but with only one domain currently attached)

Currently my problem solved.

I have got my doamin ip.

Currently my problem solved.

I am compare title for domain throw and ip throw.

I need how much sites in that shared ip. ?????

PHP: 
<?php
//call function 

get_ip('yahoo.com');

function get_ip($val)
{
    $handle = fopen('http://www.'.$val, "r");
    stream_set_timeout($handle, 10);
    
    $contents = '';
    if($handle)
    {
        while (!feof($handle)) {
            $contents .= fread($handle, 8192);
        }
        $contents    =    strtolower($contents);
        fclose($handle);
    }
    preg_match('/<title>([^>]*)<\/title>/si', $contents, $match );

    $title_name    =    "";
    if (isset($match) && is_array($match) && count($match) > 0)
    {
        $title_name = strip_tags($match[1]);
    }
    
    $sdip = gethostbyname($val);
    $handle = fopen("http://".$sdip, "r");
    stream_set_timeout($handle, 10);
    
    $contents = '';
    if($handle)
    {
        while (!feof($handle)) {
            $contents .= fread($handle, 8192);
        }
        $contents    =    strtolower($contents);
        fclose($handle);
    }
    preg_match('/<title>([^>]*)<\/title>/si', $contents, $match );
    $title_ip = "";
    if (isset($match) && is_array($match) && count($match) > 0)
    {
        $title_ip = strip_tags($match[1]);
    }
    
    if($title_name==$title_ip)
        return " - <span style='color:#FF0000; font-weight:bold'>Dedicated IP</span>";
    else
        return " <span style='color:#0000FF; font-weight:bold'>Shared IP</span>";    
}
?>
