A domain is a unique address that you are able to acquire via a registrar company. All units which are connected to the Internet, including web servers, feature numeric addresses, or IP addresses, which are very hard to remember, so the domain system was launched as an easy way to recognize a site on the Web. Thus, your website can be reached at www.domain.com instead of 123.123.123.123, for instance. A domain name includes two separate parts - the Second-Level Domain, which is the actual website name that you can choose, plus the Top-Level Domain, that is the extension - .com, .net, .org and so on. You'll be able to register a new domain name from any kind of registrar or move an existing domain between registrars in a few simple steps. If you choose to do the latter, your domain shall be renewed immediately by the gaining registrar when the transfer process is carried out. Along with the universal Top-Level Domains, there are country-code ones as well. Some of them can be registered by anybody, while others will need local presence or even a business license.
