The World Wide Web is based on unique numbers referred to as IP addresses and every device or website that is part of the Web contains this kind of an address. It really is pretty hard to remember to visit 18.104.22.168 to load a website though, that's why a much easier structure was created in the eighties - domain names. Each domain includes a main part as well as an extension, to give an example domain.com or domain.co.uk. Many different extensions exist worldwide - part of them are given to countries, for example .co.uk in the abovementioned example, which is assigned to the United Kingdom, while others are generic, like .com or .net. Various extensions are available for registration by every entity and others have certain requirements - business registration, local presence, and so on. You are able to obtain a new domain through a registrar organization such as ours and if the extension allows domain name transfers, you can relocate an existing domain between registrars too.
