The World Wide Web is based on unique numbers called IP addresses and every device or website that is a part of the Web contains this type of an address. It would be pretty difficult to remember to go to 220.127.116.11 to open a website though, that's why a much easier structure was launched in the 80s - domain names. Every single domain is made of a primary part as well as an extension, for example domain.com or domain.co.uk. A large number of extensions exist globally - part of them are given to countries, such as .co.uk in the abovementioned example, which is assigned to the United Kingdom, while others are generic, for example .com or .net. Many extensions are available for registration by any entity and some others have specific requirements - company registration, regional presence, etc. You'll be able to obtain a brand new domain from a registrar company like ours and if the extension allows domain name transfers, you can transfer an existing domain name between registrars as well.
