A domain is a distinctive address that you are able to buy from a registrar company. All units that are connected to the World-Wide Web, such as web servers, have numeric addresses, or IP addresses, which are quite hard to remember, for that reason the domain name system was introduced as an easy means to distinguish a given web site on the Internet. As a result, your web site is available at www.domain.com instead of 123.123.123.123, for example. A domain name features 2 parts - the Second-Level Domain, that is the actual web site name that you're able to select, plus the Top-Level Domain, which is the extension - .com, .net, .org and so on. You can register a new domain via any kind of registrar or migrate an existing domain name between registrars in just a few easy steps. If you choose to do the latter, your domain will be renewed automatically by the gaining registrar as soon as the transfer process has been completed. In addition to the universal Top-Level Domains, there are country-code ones as well. A number of them can be registered by anybody, while some others will require local presence or even a business license.
