The World Wide Web employs unique numbers known as IP addresses and every single unit or site that is part of the Web contains such an address. It is very difficult to remember to go to 188.8.131.52 to see a website though, that's why a much quicker structure was created in the 1980s - domain names. Every domain name contains a main part as well as an extension, for instance domain.com or domain.co.uk. A large number of extensions exist worldwide - some of them are assigned to countries, like .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, such as .com or .net. A number of extensions are available for registration by every entity and others have precise requirements - business registration, local presence, etc. You're able to acquire a new domain via a registrar company like ours and when the extension allows domain name transfers, you're able to relocate an existing domain name between registrars too.
