IP Probelm

[Al3inguy]

hi all

i have a script and it shows the user ip i used this code on it

@gettheip = split(/\./,$ENV{'REMOTE_ADDR'});

but as i know this will get the proxy ip not the real ip for the user. then i changed to this one

@gettheip = split(/\./,$ENV{'HTTP_X_FORWARDED_FOR'});


and sometimes will get the ip and some time no ip show ... so is there any way to make this code work if it can't get the REMOTE_ADDR it will get the HTTP_X_FORWARDED_FOR and vice versa .....

@gettheip = split(/\./,$ENV{'REMOTE_ADDR'}) if exists $ENV{'REMOTE_ADDR'};
@gettheip = split(/\./,$ENV{'HTTP_X_FORWARDED_FOR'}) if exists $ENV{'HTTP_X_FORWARDED_FOR'} unless exists $ENV{'REMOTE_ADDR'};

or

if (exists $ENV{'REMOTE_ADDR'}) {@gettheip = split(/\./,$ENV{'REMOTE_ADDR'});}
else {@gettheip = split(/\./,$ENV{'HTTP_X_FORWARDED_FOR'})}

BTW, you can never be certain that the IP is in fact the IP of the end-user and not some proxy in between. Not all proxies supply the forwarded-for information, and even if they do, it may represent another proxy.
