Usually you can access the client’s website pre-DNS by going to http://192.168.1.1/~username/ and preview the site before the DNS propagates.
This is especially handy because you can move files from one server to another, configure them and view them via the IP address/username combination and move the DNS after you’re confident the new server is properly setup. If executed properly, this prevents downtime and no one knows you’ve made any changes.
The problem? You can’t do this on GoDaddy. Without DNS setup, you can’t preview your site in a new location. The answer is simply to add a new A Name record pointing to a subdomain.
Configure your A Name records so that
old IP address points to yourdomain.com
new IP address points to newsiteatgodaddy.sampledomain.com hosted at GoDaddy.
and work under the subdomain until you’re ready to make your move.
