The World Wide Web employs unique numbers called IP addresses and every device or website that is a part of the Web has this kind of an address. It really is very difficult to remember to visit 18.104.22.168 to open a website though, because of this a significantly easier system was made in the 80s - domain names. Every domain name contains a primary part as well as an extension, for instance domain.com or domain.co.uk. Various extensions exist globally - some of them are assigned to countries, for example .co.uk in the aforementioned 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 every entity and others have certain requirements - business registration, local presence, etc. You can obtain a new domain through a registrar organization like ours and if the extension allows domain transfers, you will be able to shift an existing domain name between registrars too.
