The World Wide Web is based on unique numbers identified as IP addresses and every single unit or website that is part of the Web has this kind of an address. It really is very difficult to remember to visit 22.214.171.124 to see a website though, because of this a significantly simpler structure was created in the 1980s - domains. Each domain is made of a main part and an extension, for example domain.com or domain.co.uk. A wide range of extensions exist globally - some of them are assigned to countries, for example .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many others are generic, for example .com or .net. A number of extensions are available for registration by any kind of entity and others have specific requirements - business registration, regional presence, etcetera. You can obtain a new domain name via a registrar company like ours and when the extension supports transfers, you'll be able to transfer an existing domain name between registrars as well.
