The World Wide Web uses unique numbers called IP addresses and every single device or web site that is part of the Web features this type of an address. It would be very hard to remember to visit 123.123.123.123 to see a website though, because of this a significantly simpler structure was made in the 80s - domains. Each domain name includes a main part plus an extension, for instance domain.com or domain.co.uk. A wide range of extensions exist worldwide - some of them are given to countries, like .co.uk in the aforementioned example, which is given to the United Kingdom, while others are generic, for instance .com or .net. Various extensions are available for registration by any entity and some others have particular requirements - business registration, regional presence, etcetera. You're able to obtain a new domain via a registrar firm like ours and when the extension supports transfers, you'll be able to move an existing domain between registrars too.
