List of best DNS servers

Read Time:9 Minute, 6 Second

Technically, every resource (website) accessible through the Internet is hosted on some web server, and each web server has a unique IP address. To access a website, you must know the unique IP address of the server on which it is hosted. This address is a set of numbers like, or something even more complex according to the new IP address system known as IPv6.

Now naturally, memorizing such a sequence of numbers and relating them to a specific website is a difficult task for most people. Moreover, trying to remember multiple such IP addresses can quickly get very confusing since humans are used to identifying things by their names. So to eliminate this issue, the DNS or Domain Name System helps map IP addresses to easily recognizable names.

DNS servers act as bridges between hostnames and IP addresses. Whenever you enter a website URL in your web browser, your Internet Service Provider’s (ISP’s) DNS works in the background to locate the IP address of the webserver on which that website is hosted. Once it has done that, it helps fetch you the information present at that website. Thus, evidently, DNS servers are crucial to the working of the Internet.

There are multiple providers out there that offer DNS services at affordable prices. Known as third-party DNS servers, they offer several advantages over your default ISP’s DNS server. Through this post, let’s try to understand these advantages and look at a few of the best third-party DNS servers.

Why is it beneficial to use third-party DNS servers?

As already mentioned above, your ISP provides you with a DNS server by default for all your browsing needs. But looking beyond what is offered by your ISP can serve your best interests. There are several reasons for looking for alternative or third-party DNS servers:

Now that you know the benefits of using third-party DNS, let’s have a look at the best DNS servers that can serve the purpose.
