Trouble Viewing Logs

I’m having problem viewing my logs, like reading the IP adresses and the ref’s or whatever. My host doesn’t know how to do it so i’ve kind of carefully been exploring on my own. is there a certain file that reads my visitors ip’s, or records them?

and can i set up an extra IP tracker that just tracks my visitors ip’s because the one that shows up on my site has a lot of diff stuff in it. I’m totally clueless to all this.
