[Floortje]

Hi, First of all I dont know much about javascript but I do know that
basics of programming and a few languages like perl, c, and python
Im interested in a little javascript I dont understand. At
http://inet-police.com/ they seem to know my real ip adres even dough
im using an anonymous proxy. It's the second thingie in the applet. Can
anyone gimma a clue on how they do this so that I can try to figure out
how to implement such a thing in my site for certain countries (cause
someone is really frustrating my forum).

Javascript is not Java, and vice versa.

An applet runs on the browser on your computer, not on their server.
This particular applet queries the local host's name and IP address, and
obtains the external name and IP address by using an SMTP server on
their webserver. It communicates this information back in a tailored
image URL.
