You can also host sites without domain names (the so-called stop-gap domains). When you create a stopgap domain you get no DNS zone, and you cannot use e-mail service. However you will be able to access and manage your site using the instant domain alias you get at signup.
An instant domain alias is an additional web address that gives access to your website when you don’t have a real domain name or when your real domain name is temporarily unavailable. Instant domain aliases are generated randomly based on your provider’s domain name and can’t be changed. To enable or disable access to your website by instant domain alias.
