Browsers and devices may store website location data in their local system for faster access to the DNS cache. DNS Cache needs to be cleared so that a website location can be retrieved from the main server.
For those that don’t know. DNS is Domain Name Server/Service. All websites are hosted on computer servers (a fancy enterprise robust computer). These servers all have an IP address like our own computers and laptops at home do. The IP’s for servers are usually static and the same for a long time. DNS translates google.com from a name to a ip for your computer. Computers use IPs to talk to each other as their address.
