The World Wide Web uses unique numbers identified as IP addresses and every device or web site that is part of the Web contains this kind of an address. It really is pretty difficult to remember to go to 18.104.22.168 to open a website though, that's why a much easier system was made in the 80s - domains. Every single domain contains a primary part plus an extension, for example domain.com or domain.co.uk. Many different extensions exist globally - some of them are assigned to countries, like .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, for example .com or .net. A number of extensions are available for registration by any entity and some others have particular requirements - company registration, regional presence, etc. You are able to acquire a brand new domain through a registrar firm like ours and when the extension supports domain name transfers, you are able to shift an existing domain between registrars too.
