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

I don't think it's possible to know this, may be searching the string "dynamic" in the dns of the ip, but it's not always the case

You can use php_curl to save the contents of http://$IPADDRESS and
http://$SITENAME each to a separate file, run a diff on them, if they match, chances are its a dedicated IP address site.

You have two choices really to find out if ip is dedicated or shared.

1. Use google and find for a tool that does this, parse the results with PHP. Lots of tools will do this search.

2. Use msn.com, type into search: ip:IP_ADDRESS and parse the results with PHP. This is the direct way as most of the 1. option tools use this option anyways :) If only one domain appears as a result you have a dedicated IP else its shared.

None of this two is of course 100% accurate but as far as i know this is the only way to do this.
