Background information.

How does it work?

The webserver recognizes the address you're using to access our pages.

This IP Address is displayed. In some cases a proxy server does handle your connection and informs our server (by inserting a special header) about the real IP address your client uses. If this is the case, we display it for reference as well.

This technique works for IPv4 and IPv6.
