If you buy a multidomain hosting plan you will be provided with an access for two different areas: your Customer area (Link control panel), where you'll be able to manage the main domain (the one you selected as you purchased your order) and create e-mail accounts, databases and subdomains, and your Administrator area (Web host Manager), where you can create all the packages to resell to your customers, specifying all the preset resources such as disk space, e-mail accounts, etc.
For the main domain you have to use the credentials our team provided you with via e-mail during the registration process and for all the other domains you can choose your personal usernames and passwords as you wish.
If you register a new domain .it we recommend you to create hosting/DNS first and then to register your domain. That's why the Italian Nic checks the DNS of the domain you're registering: if the DNS cannot be found an error may occur.
The domain is temporary registered for 30 days. During this period the Nic will keep on checking the DNS presence for the domain. If the operation is successfully processed the domain will be registered. Otherwise, if in 30 days no DNS is found, the domain will be cancelled or charged anyway.
