The World Wide Web is based on unique numbers referred to as IP addresses and every single device or site that is part of the Web has this kind of an address. It would be very difficult to remember to visit 126.96.36.199 to see a website though, that's why a much easier system was launched in the 80s - domain names. Every single domain contains a main part as well as an extension, for example domain.com or domain.co.uk. Various extensions exist worldwide - part of them are assigned to countries, such as .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, like .com or .net. A number of extensions are available for registration by any entity and some others have particular requirements - business registration, regional presence, etc. You'll be able to obtain a new domain via a registrar firm such as ours and if the extension supports domain transfers, you will be able to transfer an existing domain between registrars as well.
