The World Wide Web is based on unique numbers known as IP addresses and every single device or web site that is part of the Web contains this kind of an address. It really is pretty difficult to remember to visit 18.104.22.168 to see a website though, that's why a much simpler structure was made in the 80s - domains. Each domain is made of a main part plus an extension, to give an example domain.com or domain.co.uk. Numerous extensions exist worldwide - part of them are given to countries, for example .co.uk in the abovementioned example, which is given to the United Kingdom, while various others are generic, for instance .com or .net. Many extensions are available for registration by any entity and some others have certain requirements - business registration, local presence, etc. You're able to acquire a new domain through a registrar company like ours and if the extension allows domain transfers, you'll be able to transfer an existing domain name between registrars as well.
