How does a DNS work?
DNS resolution is the first step taken to form an internet connection. This includes when any device is being used to access a website or any type of internet-enabled application, such as e-commerce, CRM, or food delivery. These applications are connected to the internet via IP-backbone, which is typically controlled by a protocol named BGP (Border Gateway Protocol). Each application has a unique numbering schema on the internet, referred to as IP address.
