From the Domain Center interface you can both register new domain names, and transfer your domains from another provider.
In both cases the domain extensions available to choose from are .com .net .org .info .biz .name .cloud and the service validity period is one year.
For registrations of new domain names you need to provide details of the domain owner in order to complete the purchase. For transfers, besides providing details of the owner, you need to unlock your domain with your current provider and get the AuthCode which you will need to complete the Domain Center transfer process successfully.
After completing the purchase or transfer, for each domain you can change, add or delete the authoritative DNS as and when you like through the Domain Center..
Through the Domain Center you can protect all your domains, new or transferred, from unauthorized transfers using the simple Lock and Unlock feature, or activate additional services like the "Auto-renewal" and "Whois Privacy" service.
