Many people get this confused with Hosting. This is very separate to hosting and has its own function. A Domain Name is the name of your Website URL or Address on the World Wide Web. It is the item that we point the nameservers to so that when people type your domain directly into the Address Bar of a browser, they instantly get taken to where your website is being hosted.
Domain Name Registration is created through a Domain Registrar, either through one we provide or one that you have already created a domain name through. We often prefer to manage client domains so that we can make changes to the configs that we sometimes need to make in order to give various access from server to registrar.
