The World Wide Web employs unique numbers identified as IP addresses and every device or web site that is part of the Web features such an address. It is pretty hard to remember to go to 123.123.123.123 to load a website though, so a significantly simpler system was introduced in the 80s - domains. Every single domain features a primary part plus an extension, for example domain.com or domain.co.uk. A large number of extensions exist globally - some of them are assigned to countries, such as .co.uk in the aforementioned example, which is assigned to the United Kingdom, while others are generic, such as .com or .net. Some extensions are available for registration by every entity and some others have particular requirements - business registration, local presence, etcetera. You are able to get a brand new domain name from a registrar company such as ours and if the extension supports domain transfers, you are able to relocate an existing domain name between registrars too.
