The World Wide Web uses unique numbers referred to as IP addresses and each device or site that is part of the Web contains this kind of an address. It is very difficult to remember to go to 123.123.123.123 to open a website though, so a significantly simpler structure was launched in the 1980s - domains. Each domain name features a primary part and an extension, to give an example domain.com or domain.co.uk. A number of extensions exist worldwide - part of them are given to countries, just like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while many others are generic, for example .com or .net. Some extensions are available for registration by any entity and some others have precise requirements - company registration, local presence, etc. You can acquire a new domain from a registrar company like ours and if the extension allows domain transfers, you will be able to relocate an existing domain name between registrars too.
