The World Wide Web uses unique numbers referred to as IP addresses and each device or site that is a part of the Web has such an address. It would be pretty difficult to remember to go to 123.123.123.123 to see a website though, because of this a much quicker structure was created in the 1980s - domain names. Every domain consists of a main part as well as an extension, to give an example domain.com or domain.co.uk. A plethora of extensions exist worldwide - part of them are assigned to countries, such as .co.uk in the abovementioned example, which is given to the United Kingdom, while others are generic, for instance .com or .net. Some extensions are available for registration by any kind of entity and some others have specific requirements - business registration, regional presence, etc. You can get a brand new domain from a registrar firm like ours and when the extension supports domain transfers, you'll be able to shift an existing domain between registrars too.
