The World Wide Web is based on unique numbers known as IP addresses and each device or web site that is part of the Web has this type of an address. It would be pretty difficult to remember to visit 188.8.131.52 to load a website though, because of this a significantly easier structure was launched in the 80s - domains. Each and every domain name includes a main part plus an extension, to give an example domain.com or domain.co.uk. Numerous extensions exist globally - part of them are assigned to countries, like .co.uk in the aforementioned example, which is given to the United Kingdom, while many others are generic, for example .com or .net. Many extensions are available for registration by any entity and some others have certain requirements - business registration, local presence, etc. You can get a new domain through a registrar organization such as ours and if the extension supports transfers, you are able to move an existing domain name between registrars too.
