The World Wide Web employs unique numbers referred to as IP addresses and every device or site that is part of the Web contains such an address. It would be pretty difficult to remember to go to 220.127.116.11 to load a website though, because of this a significantly simpler structure was made in the 1980s - domain names. Every domain features a primary part plus an extension, for instance domain.com or domain.co.uk. A large 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, like .com or .net. Various 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 from a registrar company such as ours and when the extension supports domain name transfers, you're able to move an existing domain name between registrars as well.
