The World Wide Web is based on unique numbers identified as IP addresses and every single device or web site that is part of the Web features this kind of an address. It is very difficult to remember to visit 18.104.22.168 to load a website though, so a much easier system was created in the eighties - domains. Every domain features a primary part plus an extension, for example domain.com or domain.co.uk. A great number 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 various others are generic, for example .com or .net. Many extensions are available for registration by every entity and some others have precise requirements - business registration, regional presence, and so on. You're able to get a brand new domain from a registrar organization such as ours and if the extension supports domain name transfers, you'll be able to move an existing domain between registrars as well.
