What exactly is a DNS? How to change your DNS?

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network.

Simplifying DNS mechanism one can say that DNS is an intelligent phonebook where network entities (computers, servers, printers etc) have a human readable name associated with their technical unique Internet address which is a sequence of numbers. 

In the end, computers connect to each other on the network by their technical internet addresses called IPs: IP (v4) or IP (v6).

A DNS server has the capability to quickly serve the IP of the named computer/entity that is accessed from your PC/laptop/tablet/smartphone. Therefore it is necessary for the functioning of your Internet browser when using URLs (Uniformed Resource Locators) and also when you send emails, since you use email addresses (which are in human readable form). Hence DNS is vital for browsing on the Net.

Why should I change the DNS?

By default the IP address of the DNS server used by your connection is set most of the time automatically by your computer, which queries this data directly from your Internet provider.

Sometimes the connection is slow or you just want to protect your privacy, or your children from harmful websites like adult ones, or those that encourage violence, drugs and/or indecent behavior.
