A domain is a unique address that you are able to get through a registrar company. All units which are linked to the Web, such as web servers, possess numeric addresses, or IP addresses, which are quite difficult to remember, for this reason the domain name system was launched as an easy means to identify a site on the Internet. In this way, your web site is available at www.domain.com in place of 18.104.22.168, for example. A domain name has two different parts - the Second-Level Domain, that is the actual site name that you can select, plus the Top-Level Domain, which is the extension - .com, .net, .org and so on. You will be able to register a new domain through any registrar or transfer an existing domain between registrars in a couple of easy steps. In the event that you decide to do the latter, your domain name will be renewed immediately by the gaining registrar as soon as the transfer process has been carried out. In addition to the universal Top-Level Domains, there're country-code ones too. Some of them can be registered by anyone, while some others need regional presence or even a business license.
