Help With Post Permalink Correction

Hi guys, I had spare time on my hands and played with my old pc to practice new things everyday, after couple days I set up server with xamp, installed wordpress and now 2 peculiar things happen. Post permalinks are htp: / localhost/domainname.com/post is there a way for me to remove the localhost part for post urls? Second thing would be that my ip is showing in the bottom left corner when page is loading is there any way to cloak it? Thanks a bunch I know its a bit on the long side

You need to setup virtual host in your httpd.conf file. Define the servername and path. Also change the url from wordpress settings.
