DNS allows to name websites, email addresses, servers, files, and basically anything you encounter being part of a local network or the internet.
You don’t have to memorize numeric IP addresses for each and every request you make.
DNS makes possible an instantaneous resolution of your request. This happens via the globally located root servers, which store databases of all TLD names and their corresponding IP addresses.
DNS is a vital component of the internet today. It’s hard to imagine how we could operate without its perfectly designed structure. Invisible to the human eye, the seamless functionality of the internet today would not exist without the DNS service.
