The World Wide Web employs unique numbers known as IP addresses and every single device or website that is a part of the Web has this kind of an address. It would be pretty hard to remember to go to 18.104.22.168 to see a website though, so a much quicker system was launched in the 1980s - domain names. Every single domain is made of a main part plus an extension, for example domain.com or domain.co.uk. A plethora of extensions exist worldwide - part of them are assigned to countries, such as .co.uk in the aforementioned example, which is given to the United Kingdom, while others are generic, such as .com or .net. Some extensions are available for registration by any kind of entity and others have precise requirements - company registration, local presence, and so on. You can obtain a new domain name via a registrar firm such as ours and when the extension supports transfers, you'll be able to move an existing domain name between registrars too.
