How can i get the ip address of machine tht are on the network.. i have tried romote address but tht gives the ip of the server to whom i am connected so what happens is all the machines on the network give the same ip using remote address but i want the individual IP of each machine... is this possible?
also is it possible to tracethe machine no of each computer thru PHP.... Please dnt let ur minds turn evil the IP so traced will help me to pass a query tht will restrict the options selected from a single machine

I'm confused...

I know on my network, my desktop computer can't host or do anything of that sort because the Internal IP Address is way to protected (and it annoys me). However, I can set my labtop computer as a server.
It depends how your network is setup, but you should be able to see the IP Addresses on your Network Places.
Since I have wireless, with microsoft software, it has a special window for showing my IP Address, and also showing all other computers on the network and shows their IP Address: Including my Linux computer.
You are looking for your internal IP Address, not your external IP Address.

you'd just have to at least know a little about how your network is set up. Here's some php manual pages about dns lookups in php.

http://us4.php.net/manual/en/function.gethostbyaddr.php (ip to name)
http://us4.php.net/manual/en/function.gethostbyname.php (name to ip)
http://us4.php.net/manual/en/functio...ostbynamel.php (ips by name)
http://us4.php.net/manual/en/function.checkdnsrr.php
http://us4.php.net/manual/en/functio...get-record.php
http://us4.php.net/manual/en/function.getmxrr.php

Keep in mind that the php functions to do this use the dns settings of the server. if the server can't see it, then neither will php.

in vpn, you're unable to view individual ip. it's because each ip is private and assigned based on "lookup table" in the gateway. anyway, if a client is connected to your server through proxy(ies) and its ip is public, you'll still be able to see the original ip. please look for constants HTTP_X_FORWARDED_FOR and HTTP_CLIENT_IP. from this, i'm sure you can find some workaround for the problem.

Hi Sowhat,

try this one.

Use the following function

PHP Code:

<?php 

function locIp() 

{ 



$ip_address=$_SERVER['HTTP_X_FORWARDED_FOR']; 



if ($ip_address==NULL){ 

$ip_address=$_SERVER[REMOTE_ADDR]; } 

return $ip_address; 

} 



$ip = locIp();



echo $ip;

?>

here's a little tip in case you are missing it, don't check the script in your local lan. proxy's are normally configured to bypass local lan's so put your code on some remote server and then try it out.

it works perfect for me using firefox, ie, netscape. I am behind squid proxy.

I am not sure about the other proxies.
