5 Best Free Public DNS Servers

Before I talk about the top five DNS servers, I’ll explain what DNS stands for. DNS stands for Domain Name System. DNS monitors the names of websites and domain names. DNS is the key component of internet service. The internet service providers automatically find the primary and secondary DNS server addresses and sends them to your computer when you are online. The DNS servers act as a sort of telephone directory for the internet service providers. Each of the DNS servers performs hundreds of look-ups a day.
