The World Wide Web uses unique numbers known as IP addresses and every single unit or web site that is part of the Web contains this kind of an address. It is very hard to remember to visit 22.214.171.124 to load a website though, so a significantly easier system was introduced in the 80s - domains. Each domain contains a primary part and an extension, to give an example domain.com or domain.co.uk. A large number of extensions exist globally - some of them are given to countries, just like .co.uk in the abovementioned example, which is given to the United Kingdom, while many others are generic, like .com or .net. Some extensions are available for registration by every entity and some others have particular requirements - business registration, local presence, and so on. You'll be able to obtain a brand new domain from a registrar firm like ours and when the extension supports domain name transfers, you can relocate an existing domain name between registrars too.
