If your domain name is registered someplace else (for example with Namecheap) then you need to update the domain’s nameservers. You will find the correct NS values in your control panel. For example, Worf’s default DNS nameservers look like: ns01.worfcontrol.com and ns02.worfcontrol.com. Their premium DNS nameservers look like: pdns01.domaincontrol.com and pdns02.domaincontrol.com. Again find the right information by logging into your web hosting cPanel.
