A domain is a special address that you are able to purchase from a registrar company. All of the units which are linked to the Internet, including web servers, possess numeric addresses, or IP addresses, which are rather hard to remember, for that reason the domain name system was introduced as an easy way to recognize a given site on the Web. Thus, your website can be reached at www.domain.com in place of 18.104.22.168, for instance. Your domain name has 2 separate parts - the Second-Level Domain, that is the actual web site name that you're able to select, as well as the Top-Level Domain, that's the extension - .com, .net, .org and so on. You will be able to register your new domain via any sort of registrar or move an active domain between registrars in a couple of simple steps. If you choose to do the latter, your domain will be renewed instantly by the gaining registrar once the transfer process is finalized. Along with the generic Top-Level Domains, there're country-code ones too. Many of them can be registered by anyone, while others need regional presence or even a business license.
