The World Wide Web employs unique numbers identified as IP addresses and every unit or web site that is a part of the Web has such an address. It really is very hard to remember to visit 123.123.123.123 to see a website though, so a much quicker system was created in the eighties - domain names. Each and every domain name consists of a main part and an extension, for example domain.com or domain.co.uk. A large number of extensions exist globally - some of them are assigned to countries, for example .co.uk in the aforementioned example, which is given to the United Kingdom, while many others are generic, like .com or .net. Some extensions are available for registration by any kind of entity and others have specific requirements - company registration, regional presence, etcetera. You can acquire a new domain from a registrar company like ours and when the extension supports domain transfers, you will be able to transfer an existing domain name between registrars too.
