The World Wide Web uses unique numbers referred to as IP addresses and each unit or web site that is part of the Web contains this type of an address. It is very difficult to remember to visit 123.123.123.123 to open a website though, that's why a much simpler structure was introduced in the 80s - domains. Every domain name features a primary part as well as an extension, for instance domain.com or domain.co.uk. Many different extensions exist globally - some of them are given to countries, such as .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many others are generic, for example .com or .net. Many extensions are available for registration by any kind of entity and some others have certain requirements - business registration, regional presence, etcetera. You can acquire a brand new domain through a registrar organization such as ours and when the extension allows transfers, you will be able to move an existing domain name between registrars too.
