The World Wide Web employs unique numbers referred to as IP addresses and each unit or web site that is part of the Web features this kind of an address. It really is very hard to remember to visit 188.8.131.52 to see a website though, that's why a much simpler system was introduced in the 1980s - domains. Each domain consists of a main part and an extension, for example domain.com or domain.co.uk. Numerous extensions exist worldwide - some of them are given to countries, such as .co.uk in the aforementioned example, which is given to the United Kingdom, while various others are generic, such as .com or .net. Some extensions are available for registration by any kind of entity and others have particular requirements - business registration, local presence, etcetera. You can get a new domain via a registrar company such as ours and when the extension supports domain transfers, you'll be able to move an existing domain name between registrars as well.
