Dns is not working in Fedora Core 1
I am having trouble with the DNS for fedora core 1. I am new to linux and I am begining to realize that the learning curve for it is steep but I am not going to give up. I decided to use Fedora as I heard it very good for the newbie. The problam I am having is this, I use adsl connection (device ppp0) to get on the net. It actavites normally (I am assuming it is as I know nothing) and when I open up terminal I can ping IP address and the gateway server for my ISP. But when I try to open up mozilla I get a error saying that the path is not found. If I put, say googles IP address in mozilla it loads up. This would lead me to believe that it is having trouble reslove domain names. I have looked around for a solution to this but I can't find anything and the stuff I do find doesn't seem to relate to me.
I was told by a freind that I may have to edit my /etc/hosts file or something along that lines. I have no idea what I would have to change in that file.
If you have any ideas, help me out.
