Do you need to transfer your domain names to your hosting service?
Ideally you should transfer to us the domain you wish to use for your site, but it is not obligatory. Transferring the domain allows us to better support you in the event of any technical issues relating to the site; and resolving problems with e-mail delivery and with the setup and configuration of your site and any other programs you might wish to run.
When you transfer the domain you do not transfer ownership of the domain, just the administrative and technical control. See How to transfer your domain. This article also covers how you should configure your web forwarding in the event that you do not wish to transfer control of the domain.
You can also transfer domains that you might use for domain mapping, but there is no real reason to do this unless you specifically want the domain mapped to your website (if you don't know what this means, you almost certainly don't need it!). In most cases where you have additional domains (e.g. your site is on "yourdomain.com" and you also own "yourdomain.co.uk" and "yourdomain.net") web forwarding to the hosted domain is recommended, in which case it not necessary to transfer the other domains.
If you haven't yet purchased your domains, you can order your main domain at the same time you order the webspace from us - we are authorised Domainbox resellers. If you want to purchase multiple domains and forward them to your site then we can register them for you, and point them to your website.
