Domain name system or commonly known as DNS is a system that translates domain names into IP addresses. Whenever we write a website’s URL into the address bar of our web browser, the browser sends the URL to the default DNS server, the server then translates the URL into an IP address and the contents of that IP address are retrieved back to your web browser. The only reason why domain name system exists is because domain names are fairly easy to remember while trying to remember IP addresses is quite hard. DNS serves as a phone book; it binds a domain name to its respective IP address.
Why do we need to change DNS server?
Usually, your Internet service provider(ISP) provides default DNS server for your internet connection, but it can get slow due to high loads, which can cause slow browsing. Your ISP can also track your internet activity through your DNS, and also block websites through it. The only way to avoid all these problems is to change your primary DNS server with custom one.
