The World Wide Web employs unique numbers called IP addresses and each device or web site that is a part of the Web features such an address. It would be pretty hard to remember to go to 123.123.123.123 to load a website though, so a much simpler system was made in the eighties - domain names. Every single domain name is made of a main part as well as an extension, for instance domain.com or domain.co.uk. Numerous extensions exist globally - part of them are given to countries, just like .co.uk in the abovementioned example, which is assigned to the United Kingdom, while various others are generic, like .com or .net. Various extensions are available for registration by any kind of entity and some others have certain requirements - company registration, regional presence, etcetera. You are able to acquire a brand new domain name from a registrar firm such as ours and if the extension allows transfers, you are able to transfer an existing domain between registrars as well.
