Best Free Public DNS Servers: In this post I am going to tell you about best free public dns servers. DNS is a short form of Domain Name System or Server. DNS is a common term in Internet world. I can say without DNS, you can not browse the Internet.

Domain Name Server is a vital part of Internet Architecture. DNS simply translates Domain name in to IP Address. Every time you connect to the internet, your ISP automatically assign required DNS addresses to your connection. With out DNS, you can not be able to open any web page on Internet. DNS is like a phonebook for the Internet which contains hostname and their respective IP address. Whenever, your web browser send request for resolving a host name like www.facebook.com, it translates this hostname into its IP address which is 173.252.110.27. Imagine a situation when you need enter the IP address to open a particular website. How can you remember thousand of IP address? Thats why here are hostname and DNS makes it super-easy to open any site by just entering its hostname like www.google.com.

A DNS system consists of two type of servers:

  • Authoritative DNS Server
  • Recursive DNS Server

Authoritative DNS Server are the computer system which actually contains the required information of website or hostname and it also knows the mapping of Hostname to its IP address. They are source of information for Recursive DNS Servers. These servers are mostly manged by Web hosting companies.

On other hand, whenever your browser send the request for a web page, this request first will be sent to recursive DNS Servers. These servers are usually manged by ISP or any other organization like Google, OpenDNS and many more. This post is all about best recursive dns servers or best public dns servers.

Why I am recommending you to use public dns server rather than ISP’s DNS. It’s because ISP’s DNS servers are not optimized to take the load of request and can not provide fast speed to your internet connection. At peak internet hours, your connection will surely suffer slowness, if you are using ISP’s DNS. If it goes down, you will not be able to browse the web, unless it went up. These servers are prone to any dns attacks.

While free public dns servers are optimized to take any amount of load and will provide fast speed all time. There will be no downtime for your internet, if you use public dns server as most of these servers uses anycast routing technology. If one server goes down, other server near your location will be up to server your internet needs. Also these server are fully secured to any type of security attack.
