The World Wide Web uses unique numbers referred to as IP addresses and every unit or web site that is a part of the Web contains such an address. It is very hard to remember to go to 18.104.22.168 to see a website though, so a much simpler structure was launched in the eighties - domain names. Every single domain name consists of a primary part plus an extension, for example domain.com or domain.co.uk. Numerous extensions exist worldwide - part of them are given to countries, just like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many 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, local presence, etcetera. You can get a brand new domain through a registrar company such as ours and when the extension allows domain name transfers, you are able to shift an existing domain between registrars too.
