The World Wide Web employs unique numbers called IP addresses and every unit or web site that is part of the Web has such an address. It would be very difficult to remember to visit 123.123.123.123 to open a website though, because of this a much simpler system was created in the 1980s - domains. Every domain consists of a main part plus an extension, for instance domain.com or domain.co.uk. A large number of extensions exist worldwide - part of them are given to countries, such as .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, such as .com or .net. Various extensions are available for registration by any kind of entity and some others have particular requirements - company registration, regional presence, and so on. You'll be able to obtain a new domain name from a registrar firm like ours and when the extension supports transfers, you're able to move an existing domain name between registrars too.
