ip address question (trouble with remote_addr)

[ojorus]

Hi.
I have a problem when I use the $_SERVER['remote_addr'].
I'm testing a script, and the strange thing is that remote_addr returns an
ip-address only sometimes, and not always. Why can that be?
Are there any other (better) methods of getting the ip-address?

Hi Ojorus,

That is suprising because that IP is used to send the response to.
Can you reproduce the empty $_SERVER['remote_addr'] yourself?

What setup are you using? PHP-version/OS/webserver?

One addition: according to

http://koivi.com/apache-iis-php-server-array.php

both IIS and Apache support remote_adres.

Re: ip address question (trouble with remote_addr)

Hi!
The server where the php-script is located is Apache/1.3.33. (Shared host)
X-Powered-By: PHP/5.0.4

When I test the script locally on my apache-installation, everything works
fine. But when I upload it to the server I use, the strange error occour;
the IP-address is only returned from time to time, and not always.
It also seems that when the server is quite busy, the problem increases.

I don't have a clue how to solve this...

Some IP addresses have no reverse DNS. If it's intermittent for
the SAME IP address on different hits, maybe you're having trouble
with DNS lookups.
