Please do. I'm forced by my ISP to be behind a transparent proxy and my real IP
address never matches the one displayed. If the proxy's address is banned, a
great amount of users connected via this ISP and others will be banned at the
same time. That's because the proxy belongs to the phone company who provides
the communication means.

Here's a piece of code to obtain the client's IP (from a comment in
http://www.php.net/getenv):

function getIP() {

$ip;

if (getenv("HTTP_CLIENT_IP")) $ip = getenv("HTTP_CLIENT_IP");
else if(getenv("HTTP_X_FORWARDED_FOR)) $ip = getenv("HTTP_X_FORWARDED_FOR");
else if(getenv("REMOTE_ADDR")) $ip = getenv("REMOTE_ADDR");
else $ip = "UNKNOWN";

return $ip;

}

but watch out for commas in the HTTP_X_FORWARDED_FOR result. There's some code
in the mentioned php.net address which explodes the string and returns an array.
I'm not an HTTP_X_FORWARDED_FOR expert so I don't know if the IP address to look
is the first or the last one. The comments there may help.

We already support extracting IPs from proxy headers for Squid support (see
$wgSquidServers and Setup.php). The only thing required to implement this would
therefore be to find a list of ISP proxy servers and add them to
$wgSquidServers--so it's mainly a policy issue rather than an implementation
issue (i.e. do we want to do this or not).

I'm closing this as RESOLVED INVALID for this reason; if people either want it
done on Wikimedia sites or a feature to allow $wgSquidServers to be updated by
sysop, it's probably best to open a new bug.
