A domain is a unique address that you can purchase through a registrar company. All the devices which are connected to the Internet, such as web servers, possess numeric addresses, or IP addresses, which are pretty difficult to remember, that's why the domain name system was launched as an easy means to identify a certain site on the Internet. In this way, your web site can be reached at www.domain.com as an alternative to 220.127.116.11, for example. Your domain name includes two parts - the Second-Level Domain, which is the actual website name that you will be able to select, plus the Top-Level Domain, that's the extension - .com, .net, .org and so on. You can register your new domain via any kind of registrar or move an active domain between registrars in a few easy steps. If you choose to do the latter, your domain name shall be renewed immediately by the gaining registrar once the transfer process has been carried out. Along with the generic Top-Level Domains, there are country-code ones as well. Many of them can be registered by anyone, while others need local presence or a business license.
