The World Wide Web is based on unique numbers known as IP addresses and each device or web site that is part of the Web contains such an address. It is very difficult to remember to visit 188.8.131.52 to open a website though, so a significantly quicker system was made in the 1980s - domains. Every single domain features a primary part plus an extension, for example domain.com or domain.co.uk. A plethora of extensions exist globally - some of them are given to countries, for example .co.uk in the abovementioned example, which is given to the United Kingdom, while many 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, and so on. You're able to get a new domain name from a registrar firm such as ours and if the extension allows transfers, you will be able to transfer an existing domain name between registrars too.
