The World Wide Web is based on unique numbers called IP addresses and every device or website that is a part of the Web has this kind of an address. It would be pretty hard to remember to go to 22.214.171.124 to load a website though, that's why a significantly simpler structure was introduced in the eighties - domains. Every single domain name features a primary part as well as an extension, for instance domain.com or domain.co.uk. Many different extensions exist worldwide - part of them are assigned to countries, just like .co.uk in the abovementioned example, which is given to the United Kingdom, while various others are generic, like .com or .net. Various extensions are available for registration by every entity and others have precise requirements - business registration, local presence, etc. You will be able to obtain a new domain name from a registrar firm such as ours and when the extension supports domain name transfers, you're able to shift an existing domain name between registrars too.
