Yes, by default domain registrant, administrative and contact (along with several other) information would be publicly available. Please note that contact and registrant information on .com, .net, .org, .info and .biz domain names are public records in the universally available WHOIS database. This is something over which we have no control, and a domain name cannot be registered without all the required fields of contact information being complete. Other countries and other domain registration authorities may have other policies.

You can hide registrant, administrative and contact information by purchasing whois privacy protection. Whois privacy will cost you $8 / year additional to domain registration/renewal cost. You can place an order for Whois privacy protection as domain addon from Client Area or you can submit the ticket.
