A domain is a unique address that you can acquire from a registrar company. All the units which are linked to the Internet, including web servers, have numeric addresses, or IP addresses, which are rather hard to remember, because of this the domain name system was launched as an easy means to identify a certain web site on the World Wide Web. By result of this, your web site is available at www.domain.com rather than 18.104.22.168, for instance. A domain name includes two different parts - the Second-Level Domain, that is the actual web site name that you're able to pick, and the Top-Level Domain, that is the extension - .com, .net, .org and so on. You'll be able to register a new domain through any kind of registrar or migrate a current domain name between registrars in a couple of easy steps. Whenever you decide to do the latter, your domain name will be renewed immediately by the gaining registrar right after the transfer process is 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 require regional presence or even a business license.
