The World Wide Web uses unique numbers known as IP addresses and each device or web site that is a part of the Web contains such an address. It is pretty hard to remember to visit 123.123.123.123 to see a website though, that's why a much easier structure was launched in the 1980s - domains. Each domain includes a main part and an extension, to give an example domain.com or domain.co.uk. A plethora of extensions exist worldwide - part of them are assigned to countries, just like .co.uk in the aforementioned example, which is given to the United Kingdom, while many others are generic, like .com or .net. Many extensions are available for registration by any entity and others have precise requirements - company registration, local presence, etc. You will be able to acquire a brand new domain through a registrar firm such as ours and if the extension allows transfers, you're able to transfer an existing domain name between registrars too.
