8 Public DNS You Can Use for FREE

The internet continues to grow and evolve, so do the tools and services that help us navigate it. A key component of surfing the web is a Domain Name System (DNS), which acts as a directory to translate domain names into numerical IP addresses.

To put it simply, DNS is the internet’s phonebook. Whereas every time your computer visits a website, it performs a DNS lookup; it then translates the domain name you entered (for example: yugatech.com) into the public IP address that your computer requires to load up the website.

While DNS servers are typically provided by internet service providers or private companies, there are also free public DNS servers available. Using a free public DNS can provide multiple benefits, such as increased security, faster loading times, and better reliability. Additionally, it can help protect your privacy by blocking malicious websites, as well as help filter out unwanted content. Although some services may offer additional features that are not available with other DNS providers.

This article provides a brief overview of some of the most popular free public DNS services available at the moment, but we recommend doing further research to determine which service best suits you.

The only domains that get blocked are those which phish or contain malware. Also, there’s an ‘unsecured service’ (IPv4: 9.9.9.10, IPv6: 2620:fe::10) which can come in handy to figure out if Quad9 threat feed has any false positives or if there are any DNSSEC (Domain Name System Security Extensions) errors with a certain domain.

5. AdGuard DNS

Primary DNS: 94.140.14.14
Secondary DNS: 94.140.15.15

IPv6 available

Secondary DNS: 2a10:50c0::ad2:ff

AdGuard DNS offers two sets of DNS servers, one called “Default” which blocks ads and trackers and another called “Family protection” which blocks adult content in addition to the items blocked in the “Default” servers. If you don’t want to block anything, you can use the “non-filtering” servers (94.140.14.140 and 2a10:50c0::1:ff). However, if you use the free version of AdGuard DNS, you won’t get customer support and you’ll be limited in terms of monthly requests, device access, and servers.

6. Verisign DNS

Secondary DNS: 64.6.65.6

Verisign is also a great choice for those who are looking for a safe and reliable connection to the internet for free. It boasts 13 authoritative servers that form the backbone of its services, providing fast and stable connections to customers all over the world.

OpenNIC is an excellent choice for anyone looking for a fast and uncensored DNS provider. It’s run by a network of volunteers who provide server resources, and users are given a list of the closest servers to their location.

However, one downside is that it doesn’t come with security features to protect you from fraudulent websites. So, it’s important to download a browser extension or antivirus software to keep trackers, malware, and ads at bay.
