The World Wide Web employs unique numbers referred to as IP addresses and every device or web site that is part of the Web has such an address. It would be pretty difficult to remember to visit 123.123.123.123 to load a website though, that's why a much simpler structure was introduced in the 80s - domain names. Each domain includes a primary part as well as an extension, for instance domain.com or domain.co.uk. A great number of extensions exist worldwide - some of them are assigned to countries, for example .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, for instance .com or .net. Various extensions are available for registration by every entity and some others have particular requirements - business registration, regional presence, etcetera. You will be able to get a new domain through a registrar organization like ours and when the extension allows domain transfers, you're able to shift an existing domain between registrars as well.
