Every internet website has a unique numeric ip address of up to 12 digits like 18.104.22.168. You can type in the ip address of any website to display it in your browser. e.g. http://22.214.171.124
The domain name system (DNS) was invented to translate the arcane ip address into a unique memorable domain name like redplug.com. If a website has registered a domain name, you can type it in to display it in your browser. e.g. http://redplug.com
Marketing your website is much easier with a domain name.
