andre3 Posted July 24, 2009 Share Posted July 24, 2009 Hey guys, when i use this to return someones ip: $_SERVER['REMOTE_ADDR']; it returns the server ip address, an it happends because www is handled as a forward on my server , however i use this function to get the persons real ip address: public function original_ip() { if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share internet { $ip=$_SERVER['HTTP_CLIENT_IP']; } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy { $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip=$_SERVER['REMOTE_ADDR']; } return $ip; } but when i capture the ip address in a sql table, some of them are like this: 195.189.142.252 , 10.22.333.33 that i want to know is, which is the persons real ip address ? i did a explode on it, to get one ip address instead of 2, an it worked farely well.. although ive done that the mystery questions remains, 'which is the real ip' i would really appreciate some help. Thanks Quote Link to comment Share on other sites More sharing options...
MadTechie Posted July 24, 2009 Share Posted July 24, 2009 The first one is the clients IP and the ones after (maybe more then one) is the proxies IP EDIT: okay I should also say that this is true for transparent proxies but NOT true for anonymous proxies. if HTTP_X_FORWARDED_FOR exists then a proxy is being used but a distorting proxy with give you a random number in HTTP_X_FORWARDED_FOR, but in a highly anonymity proxy you will not see HTTP_X_FORWARDED_FOR or HTTP_VIA Quote Link to comment Share on other sites More sharing options...

MadTechie Posted July 24, 2009 Share Posted July 24, 2009 What part don't you understand ? The first IP is the likely clients IP, but that's not always true, for example distorting proxy will give you fake info and a highly anonymity will only give you the proxy IP without setting HTTP_X_FORWARDED_FOR or HTTP_VIA Quote Link to comment Share on other sites More sharing options...
