What is DNS and How Does it Work?

DNS stands for Domain Name System, which forms the foundation of the internet—essentially it is a hierarchy of Name Servers which functions at the global scale and helps translate URLs into computer-friendly lingo i.e. IP addresses. You are thus able to connect and surf the World Wide Web.

On the other hand, a DNS server is a fundamental part of the Domain Name System, in that it hosts these URL to IP translations, and helps browsers load online resources when requested. So, if we think of the Domain Name System as a phone directory, then DNS servers are where this directory is hosted. Since with over 300 million domain names, a single-source directory would be too large to be feasible, DNS servers located around the world communicate with each other on a regular basis.

Now, if this translation facility is not working right, you are sure to face a myriad of issues. Usually, the DNS servers employed by your ISP should work fairly well. For example, Spectrum DNS Servers are geared to ensure you receive the full benefit of Spectrums fast internet speed and remain protected too. Then again, you may be able to find a free DNS server that is better suited to your location.

People often change the DNS server to improve the performance of their internet and up their security among other things. Changing it, however, requires that you cough up the money. But, if you are willing to find ways that get it done for less or free altogether, we can tell you all about it and more.

Here well discuss what you should be looking for in a new DNS server, and also share with you some of the best DNS servers you can use in 2020 without incurring a cost.

The Perks of Changing Your DNS

As we said earlier, a DNS server plays a crucial role in your online experience, and changing it can change everything!

The location of your DNS is closely connected with the speed you get, and changing it can get you a better speed. If you are also looking to keep your nosey ISP out of your business, changing the DNS server will prove worthwhile. This way, they wont be able to keep minute by minute track of your browsing history. Knowledge is power. And, without all the data they cant bombard you with advertisements that well. Better still, they wont be able to sell your data either. Whats more, using a third-party DNS protects you from security attacks like malware, phishing, and ransomware.

Additionally, changing your DNS server has benefits besides improved internet performance and online security. It helps you unlock the content blocked in your region, or any region really. So, if you want to catch up on a show on Netflix or the likes, unavailable in your area, youll be able to do that with a change in your DNS server.

Knowing this, were sure you cant wait to experiment with a different DNS server. So, let us explore next as to what you should consider when deciding which DNS server to use.

How to Choose the Best DNS Server

Speed is of paramount importance, sure. But, when choosing your DNS server you would do well by considering the following features as part of the criteria:

    • Does the server offer malware filtering? After all, you dont want to expose your network to a hack attack, do you?
    • Are their parental controls that you can use? With so much content online you might need tools to ensure your child does not end up with age-inappropriate content.
    • Check for resilience to distributed denial-of-service (DDoS) attacks. To put it simply, when servers experience high-volume traffic that they cant manage, the system is overwhelmed and gets compromised. Something you want to steer clear of.
    • If you are thinking about moving to a different provider in order to get access to a better DNS server, you must also ensure the provider uses multiple carriers. If not, one network outage will leave you without the internet altogether.

By making sure to check for these things, youll be able to find the best server there is for yourself. To help you out further, we have compiled a list of the best free DNS servers out there. Take a look.
