The World Wide Web uses unique numbers identified as IP addresses and every single unit or site that is a part of the Web contains such an address. It really is very difficult to remember to go to 123.123.123.123 to load a website though, because of this a much quicker system was launched in the 80s - domain names. Each domain consists of a primary part and an extension, for example domain.com or domain.co.uk. A number of extensions exist globally - 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. A number of extensions are available for registration by any kind of entity and others have precise requirements - business registration, regional presence, etc. You're able to get a new domain from a registrar company such as ours and when the extension allows domain name transfers, you'll be able to move an existing domain between registrars as well.
