You can point addon or parked domains at your Redwax Cloud Hosting account, the number of each depending on your package. Please ensure that the domain's nameservers are pointed to those indicated in your welcome email:
The changing of nameservers may take up to 48 hours.
You then need to add the domain as either a parked or addon domain in your cPanel account. You may allso move the registration over to use to simplify things if you wish - please look at the 'domains' page on our website.
If you have other queries regarding this then please raise a ticket.
