The World Wide Web is based on unique numbers referred to as IP addresses and every unit or site that is a part of the Web features such an address. It would be pretty hard to remember to visit 123.123.123.123 to open a website though, so a significantly quicker system was launched in the 1980s - domain names. Each domain name contains a main part plus an extension, for instance domain.com or domain.co.uk. A large number of extensions exist globally - part of them are given to countries, such as .co.uk in the abovementioned example, which is given to the United Kingdom, while various others are generic, like .com or .net. A number of extensions are available for registration by every entity and others have certain requirements - business registration, local presence, etcetera. You are able to get a new domain name via a registrar firm such as ours and if the extension supports transfers, you can move an existing domain between registrars too.
