The World Wide Web uses unique numbers called IP addresses and every single unit or website that is part of the Web has such an address. It really is very difficult to remember to visit 123.123.123.123 to load a website though, because of this a significantly simpler structure was created in the eighties - domain names. Every single domain features a primary part and an extension, for instance domain.com or domain.co.uk. A great number of extensions exist globally - some of them are assigned to countries, like .co.uk in the abovementioned example, which is given to the United Kingdom, while various others are generic, for instance .com or .net. Some extensions are available for registration by any kind of entity and others have precise requirements - business registration, local presence, etcetera. You can get a new domain via a registrar company such as ours and when the extension supports domain transfers, you'll be able to shift an existing domain between registrars too.
