A domain is a unique address that you're able to purchase via a registrar company. All units that are linked to the Internet, such as web servers, feature numeric addresses, or IP addresses, which are rather difficult to remember, for that reason the domain system was created as an easy means to recognize some web site on the Internet. In this way, your site can be reached at www.domain.com instead of 18.104.22.168, for example. Your domain name includes 2 parts - the Second-Level Domain, which is the actual web site name that you will be able to select, and the Top-Level Domain, which is the extension - .com, .net, .org and so on. You can register a new domain name via any type of registrar or transfer an existing domain between registrars in a couple of easy steps. When you choose to do the latter, your domain shall be renewed instantly by the gaining registrar as soon as the transfer process is completed. In addition to the generic Top-Level Domains, there are country-code ones as well. A number of them can be registered by anybody, while some others need regional presence or a business license.
