The World Wide Web uses unique numbers identified as IP addresses and every device or site that is a part of the Web has this kind of an address. It is pretty hard to remember to go to 126.96.36.199 to see a website though, that's why a much easier system was introduced in the 1980s - domains. Each and every domain name includes a main part plus an extension, for instance domain.com or domain.co.uk. A number of extensions exist globally - some of them are given to countries, just like .co.uk in the abovementioned example, which is given to the United Kingdom, while many others are generic, for instance .com or .net. A number of extensions are available for registration by any kind of entity and others have precise requirements - company registration, regional presence, etc. You are able to obtain a new domain through a registrar organization such as ours and when the extension supports transfers, you'll be able to shift an existing domain between registrars too.
