Webserver

Hello,
Can someone give me an instructions in how you configured my webserver. In my case, I built my webserver (i.e. server1 and server2) server2 where i setup my webserver and I was able to access my website via local intranet access. Now I wanted to access my website via publicly internet and I don't know how to configure that part. I did signed-up for domain at godaddy.com however I don't know which ipaddress do I set to my godaddy.com account.

Any help would be appreciated........
