Hi there.
To check a server's IP is very simple.
In every server there is a sclientinfo.xml file in the data folder or their "customdata".grf.
Open up the sclientinfo.xml with notepad and you will be able to see
<address>IP or a website adress</address>
If there is an IP, which should be like: 1**.23*.1*1.*32
Then, that is the server IP.
If the address is a link to a website, then you have to use
www.google.comand search for IP track
for example I use this link:
http://aruljohn.com/track.plthen you simply type in the website address and track the IP.
You will then find the server IP as well.
Kind regards, hope it helped
