... and the settings of your ISP's caching nameservers...
Corey, if you haven't rebooted your PC in a while and you're using windows, lauch yourself a command prompt and type:
this will clear your computer's DNS cache, and force it to pull a new IP for the domain you've likely been refreshing for the past 40 hours straight.
If you still can't pull it up, consider posting the domain here so one of us can check it for you. It could just be that your ISP's nameservers are set to cache for an unusually long time (which happens with some ISPs that have overworked DNS servers)
reading back here... I wonder, did you actually tell your webhost that you're getting a domain? - your website needs to be told to react to the domain, and you can do that via your hosting control panel, or by contacting your host.
If you did that prior to grabbing a domain from godaddy, then fine, but if not, then you will want to do that ASAP.
