A domain is a virtual address on the Internet for any organization or entity. Technically, a domain is defined as a group of networked computers that represent an organization and provide network services; however, several domains can reside on one server, in a dedicated space provided by a Web hosting service. To the Internet user, a domain appears as the space on one server, regardless of its implementation.
Domains are identified by their Internet Uniform Resource Locator (URL) addresses. Syntactically, a domain name is a string of words separated by periods.
Domains are structured in the form of an inverted tree. Each branch or leaf on the tree is labeled with a simple alphanumeric string, and a complete domain name is written by stringing all the labels together, separated by periods. Therefore, www.cloudblue.com is a third-level domain name. The root domain is com, the second level label is cloudblue, and the third level is www.
Note: You need to officially register a domain and Internet address before you create it in Operations. You can do this through any Internet registration service.
Operations gives you many opportunities to administer your domain. You can enable and disable your website support, change a DNS hosting type, create new DNS records, and edit DNS time settings.
The most important operations regarding domains are performed in Services > Domains.
