A Domain Name System or simply DNS is a way to convert human-readable domain names into IP addresses which machines can understand and process. It is often referred to as “computer phone book”. The major difference between a DNS and Phone book is that phone books do not update themselves. A DNS can dynamically change it’s settings to link users to machines even when some low-level network configuration is changed. Users benefit from that when they enter a website URL and instantly get redirected to a desired resource without doing manual set-up.
Public DNS servers
Most users use a public DNS server without ever knowing it. Most of those come as a default value in the appropriate field. That means you most likely use a public DNS server if you connect to your home WiFi network or go out and do it in a restaurant.
The issue with most DNS servers is that beside doing their primary job they often cache a lot of sensitive information and store it for who knows how long. An average DNS server has cached info about which IP’s connect to certain domains, which e-mail addresses are used to send a letter to certain addresses and other sensitive info which some users would prefer not to reveal.
