You will need to submit the following information to the registrar:
- the desired domain name
- The name and contact information (including email address, physical address and contact phone number) for the domain's registrant, administrative and billing contacts.
- the desired domain registration term
- payment information
The registry files the contact information for the Whois. The registry also adds your domain zone files to the master servers. These master servers tell other servers on the Internet where your website is stored.
