To have your domain name point to your new account with us, you will need to change some details in your domain name management area.
If you didn't purchase the domain from us, you will need to make this change on your domain registrar, the place where you purchased the domain from. You should have the information to login to your account to make the change.
The required change is often called "redelegation" or it may say "Update DNS" or "Name Servers" or sometimes it is also called "Change Host".
Click on to this area and then enter our DNS Servers as your Primary and Secondary DNS servers for your domain.
You should find which of our DNS servers you should use by going to your hosting control panel, and click Domains, and click on the domain you wish to delegate to us. The DNS servers should be displayed on this page.
Note this doesn't mean that you are transferring the registration process of your domain to us. You will maintain your current domain registrar and will continue paying them for domain name renewals.
