The World Wide Web is based on unique numbers known as IP addresses and each device or web site that is a part of the Web has this kind of an address. It would be very hard to remember to go to 22.214.171.124 to open a website though, that's why a significantly simpler system was made in the 80s - domains. Each and every domain features a main part and an extension, for instance domain.com or domain.co.uk. Numerous extensions exist globally - part of them are given to countries, just like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many others are generic, for example .com or .net. Various extensions are available for registration by any kind of entity and others have particular requirements - company registration, regional presence, and so on. You can get a new domain name from a registrar firm such as ours and when the extension supports transfers, you can move an existing domain name between registrars as well.
