The World Wide Web is based on unique numbers known as IP addresses and each unit or web site that is part of the Web features this type of an address. It would be very difficult to remember to go to 220.127.116.11 to open a website though, so a significantly quicker system was made in the 80s - domains. Each and every domain contains a primary part and an extension, for example domain.com or domain.co.uk. A great number of extensions exist worldwide - some of them are given to countries, for example .co.uk in the aforementioned example, which is assigned to the United Kingdom, while many others are generic, like .com or .net. Various extensions are available for registration by every entity and others have specific requirements - company registration, local presence, and so on. You are able to get a new domain from a registrar company such as ours and if the extension supports transfers, you're able to relocate an existing domain between registrars as well.
