Top 10 Free Public DNS Servers

DNS servers are basically databases with URL addresses and their corresponding IP address. When you connect to the internet to access services or web pages, what you use are URL addresses, so you must have a DNS server configured on your PC or mobile phone to navigate comfortably without having to remember what the address was.

Have you ever wondered what the DNS server that you use on your device to navigate is? By default, the DNS server you use is the one automatically provided by your teleoperator, but there are many more.
