Question

PHP equivalent of ASP "Request.UserHostAddress"

Asked by: daleyjem

i have tracked a certain visit to my site that has multiple IP Addresses recorded within the same Session. each one beginning:
152.163.xxx.xxx

it is tracked using PHP's "getenv('REMOTE_ADDR')"

the visitor then goes to another site of ours made with ASP. the IP not only stays consistent within this site, but also has a completely different IP address beginning:
172.167.xxx.xxx

it is tracked using ASP's "Request.UserHostAddress".

because ASP's method is consistent, i believe it is the correct IP address where as the PHP's method may be retrieving the multiple proxy IP's being used by the ISP of the visitor.

how do i obtain the same consistent IP address of the visit?

thanks,
jeremy

sorry for the low point value... it's absolutely all i have left...

Those look like AOL proxy IPs, they the client rotates IPs being used so AOL users it will switch often completely to new server.

http://webmaster.info.aol.com/proxyinfo.html will show a list of known AOL proxy ranges. An AOL user will constantly be switching between different IPs from different proxy servers.

this much i figured out... but why is the IP i retrieve through PHP changing, but the IP retrieved through ASP consistent? is this just circumstantial, or is the ASP method retaining the "correct" IP?

 

by: CrYpTiC_MauleRPosted on 2005-08-15 at 13:59:06ID: 14678047

Well AOL proxy servers are used for caching to load balance requests to various content. Complex thing to do with 30+ million users, so would have to ask AOL why the IP is not being rotated on the ASP page and not on the PHP page. But both retrieve the same value, just depends on AOL when IP is rotated or if it is at all.

 

by: daleyjemPosted on 2005-08-16 at 05:15:01ID: 14681787

would i be getting a different value for AOL if i were using a different method such as:
"HTTP_X_FORWARDED_FOR" or even "HTTP_CLIENT_IP"? i'm not exactly sure of which either one of them do, or if they even return a different value than "REMOTE_ADDR"...
