Finding a certain server

One of my friends at school has been playing on this one server, and it seems pretty cool, I asked for the IP and he forgot several times, so I'm taking it into my own hands to find out the IP, I know there are several factions on this server, so here they are

Red Army
The Cold Brotherhood
The Dead Miners
The Legion (of the server)
The Team
The woodlands

Those above are some of the factions and my friends username is
Kaipyro67

If anyone has the IP, please send me it.
