Description:

This is about the german translation of the description of the predefined variable $_SERVER['REMOTE_ADDR']

Documentation: English original:
http://www.php.net/manual/en/reserved.variables.php
'REMOTE_ADDR'
    The IP address from which the user is viewing the current page. 

This is partly correct. If there is no proxy, it is the IP address of the user's computer. If there is a proxy, it is the IP address of the proxy.

German translation:
http://www.php.net/manual/de/reserved.variables.php
'REMOTE_ADDR'
    Die IP-Adresse des Servers, von dem die aktuelle Seite geladen wurde. 

The word "Server" seems wrong and confusing to me. 
To me, the words "server" and "client" have the following meaning: On one side of the internet, there is the user ("client"), on the other side, there is the webserver with PHP ("server").
Thus, $_SERVER['REMOTE_ADDR'] contains the IP address of the "client".

I suggest the following translation, which also is technically more precise/correct:
"Die IP-Adresse des Rechners, der die aktuelle Seite angefordert hat."

("The IP address of the computer that requested the current page.")
