The World Wide Web uses unique numbers known as IP addresses and each device or site that is part of the Web has such an address. It really is pretty difficult to remember to visit 123.123.123.123 to load a website though, so a much easier structure was made in the 80s - domain names. Each domain includes a main part plus an extension, for example domain.com or domain.co.uk. A large number of extensions exist worldwide - some of them are given to countries, such as .co.uk in the abovementioned example, which is given to the United Kingdom, while various others are generic, such as .com or .net. A number of extensions are available for registration by any entity and others have precise requirements - company registration, regional presence, etcetera. You'll be able to acquire a brand new domain name through a registrar firm such as ours and if the extension supports domain name transfers, you are able to transfer an existing domain name between registrars as well.
