When you purchase an web address (domain) information is sent to a company called the domain registrar. The domain registrar manages that web address and records certain things, such as who currently 'owns' that domain and their personal details.
This information is entered into the registrar's database so that a record of who manages a domain can be queried. A query is commonly referred to as a whois lookup, and an example website from is our Gradwell Status Network Tools page. If you enter gradwell.com into the Host to lookup search box on that website you'll find information on the registrant (in this case, Gradwell), including who to get in touch with if you have queries about the domain.
If you have registered a domain and wish to update any of this information, you can do it through your online control panel.
After logging on click Registered Domains.
You will see a list of all the domains on your account. Select the domain that you wish to edit.
If you wish to edit the contact information for your domain, scroll to the Contact Info section and click the Manage Contacts button.
You may need to add new account administrators if you wish to update contact information. For information on adding new account contacts, please see this article.
If you wish to change the nameservers (which contain your zone file and are important in routing visitors to your website and correctly routing email that is sent to you) then click on Manage Nameservers).
