From Lunarpages Web Hosting Wiki
To make your domain name registered with another Registrar work with your web hosting here at Lunarpages, you will need to update your nameserver settings. Your nameservers that you should use are included in your welcome e-mail. If you can not find them there, you should also be able to find them in the Customer Account Page.
After you log into CAP, click on the icon for Hosting Information on the top left, and you will see them as in the image above.
Once you have your two nameservers you can go to your Registrar and update them to point to your Lunarpages account.
- Please note: It can take from 24 to 72 hours for your new nameserver information to propogate.
