The World Wide Web uses unique numbers called IP addresses and each unit or web site that is part of the Web features such an address. It is very hard to remember to visit 123.123.123.123 to see a website though, so a significantly simpler structure was introduced in the eighties - domain names. Every domain name contains a primary part as well as an extension, for instance domain.com or domain.co.uk. Numerous extensions exist worldwide - part 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, for example .com or .net. Some extensions are available for registration by any kind of entity and others have certain requirements - business registration, regional presence, etcetera. You can obtain a new domain name from a registrar firm like ours and when the extension supports domain name transfers, you will be able to shift an existing domain name between registrars too.
