Far Cry Server Problems

I play Far Cry and now that the game is old, there are still many players playing (the game is really fun). The problem that I have is there are a couple of hackers that have created their servers and they crash all other servers so we have to go to their server to play. The game is unfair now with about 90 percent are hackers. I still love the game and I only joined this so when the hackers crash all the servers, I can crash theirs. The Far Cry server with the ip address of: 5.231.197.10:49001, 5.231.197.11:49001, 5.231.197.12:49001, 5.231.197.13:49001 and 5.231.197.14:49001. He calls his server: *NEW* FPFC.eu Server and he has various names such as Assault 1.4 or 1.6. Bottom line is I am tired of him controlling who can play and when on only his server. I got into a argument and now he did a IP ban on me so now his servers show up grey and I cannot play on them. But he crashes all the server so everyone goes to his server. End result is I don't get to play now since he has done this. How do I unban a ip ban? Can I change my ip?? You can tell that I do not know very much about this subject and I really need some help so these guys do not control my favorite game. Thank you very much and please help me please.
