The World Wide Web is based on unique numbers called IP addresses and every unit or web site that is a part of the Web features such an address. It is pretty difficult to remember to visit 18.104.22.168 to see a website though, so a much easier system was created in the 1980s - domain names. Each and every domain includes a main part and an extension, for instance domain.com or domain.co.uk. A great number of extensions exist worldwide - some of them are assigned to countries, for example .co.uk in the aforementioned example, which is assigned to the United Kingdom, while various others are generic, like .com or .net. Some extensions are available for registration by every entity and others have particular requirements - business registration, regional presence, and so on. You can get a brand new domain name through a registrar firm such as ours and if the extension allows transfers, you are able to move an existing domain between registrars too.
