Yes, if you wish to see your website before the domain is propagated fully, you can:
1. Order a dedicated IP address for your account, and when you enter this IP into your browser, your website will be displayed;
or
2. Enter the IP, a forward slash, a ~ before your username. For example, if the IP is 2.4.6.8 and your username is demotest, you'd put http://2.4.6.8/~demotest. be aware that this is best with static html sites, if you use PHP and databases, it may result in abnormality.
