The World Wide Web employs unique numbers identified as IP addresses and every single device or web site that is a part of the Web contains this type of an address. It is pretty hard to remember to go to 123.123.123.123 to load a website though, that's why a significantly quicker system was created in the 80s - domain names. Each domain name is made of a primary part plus an extension, for instance domain.com or domain.co.uk. Many different extensions exist globally - part of them are given to countries, like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while others are generic, such as .com or .net. Many extensions are available for registration by any kind of entity and others have particular requirements - business registration, local presence, etc. You're able to acquire a new domain from a registrar firm such as ours and when the extension allows transfers, you're able to shift an existing domain between registrars too.
